A little more on Quantum Entanglement and Teleportation

Fundamental particles all have a quantum state called spin. Quantum entanglement means that if one particle has a spin of up, then its partner will have a spin of down and any change in the quantum state of one particle will alter the spin of the other.

Everything in the universe is made up of the fundamental quantum bits and that allows us to view everything as a collection of information stored in qubits. We are not entirely sure how quantum teleportation works but it could be some sort quantum tunnel that opens allowing the quit to bypass spacetime. Multiple experiments have been done demonstrating that the electronic state of an atom can be transferred from one place to another instantaneously.


In quantum computing, qubit or quantum bit, is a unit of quantum information—the quantum analogue of the classical bit.

A qubit is a two-state quantum-mechanical system such as the polarization of a single photon: here the two states are vertical polarization and horizontal polarization. In a classical system, a bit would have to be in one state or the other, but quantum mechanics allows the qubit to be in a superposition of both states at the same time, a property which is fundamental to quantum computing.

Quantum RAM: Modelling the big questions with the very small

Griffith’s Professor Geoff Pryde, who led the project, says that such processes could be simulated using a “quantum hard drive”, much smaller than the memory required for conventional simulations.

“Stephen Hawking once stated that the 21st century is the ‘century of complexity’, as many of today’s most pressing problems, such as understanding climate change or designing transportation system, involve huge networks of interacting components,” he says.

“Their simulation is thus immensely challenging, requiring storage of unprecedented amounts of data. What our experiments demonstrate is a solution may come from quantum theory, by encoding this data into a quantum system, such as the quantum states of light.”

Einstein once said that “God does not play dice with the universe,” voicing his disdain with the idea that quantum particles contain intrinsic randomness.

“But theoretical studies showed that this intrinsic randomness is just the right ingredient needed to reduce the memory cost for modelling partially random statistics,” says Dr Mile Gu, a member of the team who developed the initial theory.

In contrast with the usual binary storage system - the zeroes and ones of bits - quantum bits can be simultaneously 0 and 1, a phenomenon known as quantum superposition.

The researchers, in their paper published in Science Advances, say this freedom allows quantum computers to store many different states of the system being simulated in different superpositions, using less memory overall than in a classical computer.

The team constructed a proof-of-principle quantum simulator using a photon - a single particle of light - interacting with another photon.

They measured the memory requirements of this simulator, and compared it with the fundamental memory requirements of a classical simulator, when used to simulate specified partly random processes.

The data showed that the quantum system could complete the task with much less information stored than the classical computer- a factor of 20 improvements at the best point.

“Although the system was very small - even the ordinary simulation required only a single bit of memory - it proved that quantum advantages can be achieved,” Pryde says.

“Theoretically, large improvements can also be realized for much more complex simulations, and one of the goals of this research program is to advance the demonstrations to more complex problems.”

Happy Endings and Potentiality

I have to share this thing about W and quantum physics for a sec, because the way this show plays with time and parallel universe theory just pushes all of my nerdy Sci-Fi-loving buttons, and I need everyone to know how smart Song Jae Jung is.

So first off: let’s talk multiverse theory. 

There’s a theory in quantum physics that states that, as there are multiple potential outcomes for every decision you make (and each outcome is as equally likely to happen as the next), it must therefore be true that every potential outcome of every possible decision is playing out right now, simultaneously.

For example, this means that even though you are eating a granola bar for breakfast right now, in another universe at the exact same time, you are eating a bowl of cereal. At the same time, in another universe lying parallel to that, you chose to eat toast. And in another universe lying parallel to that, you’re running out the door because you didn’t have time for breakfast. All potential actions are acted out simultaneous to each other, but no outcome is repeated within the same universe. If two universes have the same outcome, then they are (by this definition) in essence, the same universe.

Now let’s talk about W.  

 Song Jae Jung embraces the multiverse theory in the way she writes the show, and she does it in a really clever way. I’m going to explain to you how. 

 So W takes place in a multiverse, right? That’s established at the very beginning: there are two universes in W, the one where Yeon Joo lives, and the other where Chul lives. It therefore stands to reason that W takes place in a reality where multiple universes (not just those two) exist at the same time.

We are constantly told how the story is going to end, only for the show to alter its trajectory as soon as we’ve been told its projection. Song Jae Jung starts doing this subtly in the comic’s universe… but as the comic’s story connects the two universes together, she starts to bring this into the very fabric of the way she structures the drama. In fact, it’s because of multiverse theory that Chul and Yeon Joo can even fall in love to begin with: once their universes begin to share the same outcome, they are technically living in the same universe, according to the theory.

I have to spell this out, because it is just so cool to me:

Poem Thing

Okay so I was rereading some of my WIP’s, and I meant to write, but then I started saying a poem. So instead of saying it, you all get the poem i typed out of it. Additionally, this is actually like a rough outline of the next multi chaptered work I’m trying to write by myself. I have no clue what the plot is, aside from Castiel x Reader. And it comes from the heart (and my own personal fantasies). But I have 2900 words written and it is killer. Heavy on the Quantum!Cas, with a bit of Quantum!Reader too. Very plotty.

Anyway. Spoilers. Here’s the rambling my mind did this afternoon:

You stood there, glaring out into the night

It came

It slashed

You fell

Laying there bleeding on the ground

Close to death.


Come two men

Barreling in

Really tall plaids, the both of them

They stabbed it

Really did kill it

Kill it to death.

And then

They saw you

Bleeding all over the grass

Taking your last breaths.

The shorter one prays

Calling for an angel from on high

Will this be the last sound you hear?

A prayer from a stranger?

But then

A miracle

Another man arrives

But he is not really a man-

No, its an old hallucination.

You reach out

Limbs weak

Crying ‘Tom, Tom’

‘You’ve come to take me home’

‘I have waited ever so long’

He kneels,

Puts two fingers on your forehead,

And then-

A shock.

No more pain

No wounds

Just tears on your blouse.

You sit up; confused

Why did he do that?

He know how much you’ve longed for release

From this life

This form-

All so restricting.

You tell him so.

‘It’s not your time yet’

He replied

Deep and mysterious.

You sigh,


‘Fair enough’

You say,

And stand up,

Staying right next to him- Your guardian angel.

From my notes of:

The reader is close to death from wounds from a monster when the Winchesters come barreling in, killing it. They call Castiel to heal her. She is delirious, talking about her angel has come down from Heaven to take her home. She calls him Tom, and how she has waited so long.

Cas heals her, at which point she sits up, very confused. Asks why he did that; that he knew that she wanted to go. He said that it was not her time yet. She sighs and nods, standing up and very close to him.

Gaster’s entry number seventeen explained:
This experiment has a lot to do with light, and a bit of quantum mechanics.

First off, “photon readings negative”. For those who don’t know, photons are a rest-massless particle that travels at the speed of light, and is responsible for all electromagnetic waves including the visible light spectrum. It’s hard to explain without getting so complicated that most people will get lost. Basically, think of photons being bits of light and all electromagnetic radiation.

How bright something is and what color it is depends on the amount and wavelength of the photons being reflected off of it and hitting your retina. There’s tons of photons everywhere. If we didn’t have photons, we couldn’t see, and electromagnetic waves would have nothing to act as a force carrier.

This is vastly oversimplifying it, but basically if a test came back with photon readings negative, that would mean the sensors did not get hit by any photons, that absolutely none of the ambient photons or projected photons like with a laser were reflected. Something absorbed or transported those photons.

So if something were absorbing or transporting some photons, the area it takes up would appear darker, as only a few photons would hit it or pass through it and bounce back to our retina. If it got darker and darker, that means less and less light is being reflected back. We have made Vantablack, a material that absorbs so much light that it is the closest thing to “true black” or “true darkness” possible, our human eyes can not determine its 3D form because of this, it’s similar to playing a game with some textures being a pure flat black or without shading. Still, no material can absorb all photons.

Whatever Gaster was experimenting with, it was growing in volume, absorbing more and more photons until it absorbed all the photons that come into contact with it. It transported the photons or somehow converted them into something allowing it to grow with 100% efficiency. This creates a substance so dark, no light can reflect off it, no radio, gamma, infrared, ultraviolet, or x-rays could pass through or reflect off it. It would be in effect a 3D hole in the universe, that is slowly growing. Imagine seeing a pure black 2D shape, that no matter the position you look at it, it looks 2D, shining a laser or flashlight at it doesn’t do anything. It casts a perfect shadow. And it’s growing. It would be incredibly cold as it would transport any heat radiation. Honestly, I don’t know enough quantum mechanics to tell you what would happen if you touched it, and what effect it would have on matter if it absorbed all photons that contacted it. It would make the entire area darker.

Needless to say, it would be very interesting, and very complicated. For the sake of not having to explain Einstein’s theories and a great load of formulae and mathematics, I’ve simplified it for you.

Now there remains a lot of questions about this, like who the other two are, but remember that book on quantum mechanics back in San’s home?… I think this may be connected.

I may have to explain the multiverse theory and what Sans says, but that’s for another much more complicated and confusing post.

over the next few hundred years, if artificial intelligence does not all together enslave or destroy mankind, humans will live in an increasingly virtual world. plants, food, buildings, jobs, ect. will be replaced by their virtual equivalent. eventually, humans will be unable to decipher between what is virtual and what is real. obviously this will result in the digitalization of humans themselves. no longer will we be physical and natural forms borne from this great mother earth, but we will be a collection of qubits. i say qubits instead of bits because quantum computers will have replaced classical computers by this time, but who knows, we may have something even more advanced than quantum computers. 

i predict elon musk will be our virtual overlord. since the earth was going to die as a result of pollution and possibly nuclear war, elon musk digitalized the earth. i know what you’re going to say… a digitalized earth and humans may be superior to real earth and humans. after all, if humans are technological beings, we would also be more rational beings. and if we’re all just made of qubits there will be no reason to hate one another based on exterior differences. obviously, this is not true. the world, virtual or not, will forever be divided. different groups of virtual humans are bound to decide that their programming is the superior programming. it is my worst fear that this will result in a horrible virtual war. elon musk, our benevolent overlord, will try and save us, but unfortunately we will tear each other apart. people will discover ways to hack the virtual brains and bodies of their enemies. this will eventually result in the end of the virtual world, and thus humanity all together. though, that begs the question… if we are all turned into virtual beings, on a virtual worlds, would the concept of humanity still be something we could apply to ourselves? i’d argue yes, because humanity has simply shifted and taken on a new form. 

D-Wave smashes quantum computing record with 1,000 qubit system
1,000 qubit processor calculates more possibilities than there are particles in the universe.

Quantum computing company D-Wave Systems has unveiled the world’s most powerful quantum computer processor, double the size of previous generations used in the ultra-powerful machines.

At 1,000 qubits, the new processor is capable of considering 21000 possibilities simultaneously. To give an idea of the size of such processing capabilities, this new search space considers more possibilities simultaneously than there are particles in the observable universe.

“For the high-performance computing [HPC] industry, the promise of quantum computing is very exciting,” said Earl Joseph, programme vice president for HPC at D-Wave.

“It offers the potential to solve important problems that either can’t be solved today or would take an unreasonable amount of time to solve.”

The development puts D-Wave at the forefront of the nascent quantum computing industry, which has been widely touted as holding revolutionary potential in a variety of fields due to the immense processing power of the machines.

The CIA, Google and NASA are among the organisations currently researching the technology through the use of quantum computers made by D-Wave.

Earlier this year, the UK government joined the list of interested parties by announcing a new £270m ($424m) strategy into quantum technology growth through the UK National Quantum Technology Programme.

The 1,000 qubit milestone surpassed by D-Wave represents a “triumph” over design and performance challenges, according to the company, and will be on display at the upcoming GEOINT conference in Tampa, Florida.

“Breaking the 1,000 qubit barrier marks the culmination of years of research and development by our scientists, engineers and manufacturing team,” said D-Wave CEO Vern Brownell.

“It is a critical step toward bringing the promise of quantum computing to bear on some of the most challenging technical, commercial, scientific and national defence problems that organisations face.”

What is quantum computing?

Quantum computers replace traditional bits that are used in digital communications with quantum bits, or qubits. Potential applications can be found in a variety of fields, from medicine to space travel.

Qubits exist in a state of superposition, meaning they can be in both states at once, rather than restricted to either binary state as traditional bits function.

Quantum Computing Is Real, and D-Wave Just Open-Sourced It
The company behind Google's quantum computer is releasing open source tools so coders can create software without needing an advanced physics degree.


QUANTUM COMPUTING IS real. But it’s also hard. So hard that only a few developers, usually trained in quantum physics, advanced mathematics, or most likely both, can actually work with the few quantum computers that exist. Now D-Wave, the Canadian company behind the quantum computer that Google and NASA have been testing since 2013, wants to make quantum computing a bit easier through the power of open source software.

Traditional computers store information in “bits,” which can represent either a “1” or a “0.” Quantum computing takes advantage of quantum particles in a strange state called “superposition,” meaning that the particle is spinning in two directions at once. Researchers have learned to take advantage of these particles to create what they call “qubits,” which can represent both a 1 and a 0 at the same time. By stringing qubits together, companies like D-Wave hope to create computers that are exponentially faster than today’s machines.

Quantum Computers Don’t Make Sense. But This One Makes Music
IBM demonstrated a working quantum computer in 2000 and continues to improve on its technology. Google is working on its own quantum computer and also teamed up with NASA to test D-Wave’s system in 2013. Lockheed Martin and the Los Alamos National Laboratory are also working with D-Wave machines. But today’s quantum computers still aren’t practical for most real-world applications. qubits are fragile and can be easily knocked out of the superposition state. Meanwhile, quantum computers are extremely difficult to program today because they require highly specialized knowledge.

“D-Wave is driving the hardware forward,” says D-Wave International president Bo Ewald. “But we need more smart people thinking about applications, and another set thinking about software tools.”

Quantum leaps into the public’s hands.

Lasers. Transistors. Flash memory. Quantum theory has led to many technological advances. While we have yet to determine if it really makes time-travel possible, we do know what it can do for computing. Quantum computing has binary bits, just like any computer. But instead of ones and zeros, its quantum bits, or qubits, can represent a one, a zero, or both at once (a phenomenon known as superposition and the beginning of a rather long rabbit hole…)

At first, only a close group of physicists and engineers could participate in quantum computing projects. Now, IBM is opening up the IBM Quantum Experience to the public. In the Quantum Experience, anyone will be able to create algorithms for and run experiments on our quantum processor through personal desktops or mobile devices. Curious minds will also be able to play with qubits, find inspiration and learn about quantum through tutorials and simulations. The race is on to see just what other kind of leaps we can make.

mrdoctorprofessorten  asked:

Have you seen the newest Game theory from Matt Pat on undertale and if so what do you think about it?

Just watched it ahhh, didn’t really interest me a lot but you’re not the first to ask so I went and did it this morning.

While I can appreciate the idea of Sans having once been on the surface, I feel that many theorists forget the other things he’s had to deal with, and that his knowledge of celestial bodies can have loads to do with his involvement with quantum physics.

As someone who used to read up a bit on quantum physics, along with cosmic string theory and the idea that bending such strings could allow for time travel, I feel that this is a very important thing about Sans to overlook. Papyrus knows Sans like space sci-fi stuff, especially when it’s real, Sans could know everything theoretically about the Sun, stars, and other large space things from dealing with quantum theory, as those forces are pretty important in reference to understanding your own world. His knowledge of quantum physics can also explain how he is in multiple places seemingly at once. I prescribe to the idea that it’s not that he has multiple sentry stations, he’s using a mix of magic and quantum physics to simultaneously place a singular sentry station across several locations. Which is important, because he shows off this ability on Gyftrot’s cliffside and it can reasonably explain his “teleportation”.

It’s also possible that Sans “giving up on going back” had loads to do with dealing with Flowey. While Flowey was never able to beat Sans while he had control over the timeline, Flowey did a lot to mess with everyone over and over, and if we follow the theory that Sans always knew an anomaly would show up in the timeline, he’s dealt with not just the player character but Flowey for an unknown amount of time. Poor dude must be tired.

We don’t know how different the underground was before Flowey messed around with things, or for how long Flowey had influence over the timeline. And I am beginning to like the idea, with how much Sans is aware of things like statistics, that he is also fully aware that the timeline, the copy of the game, he’s in with you is one that can’t go back beyond when Frisk falls into the underground. So, he’s given up.

I don’t really like theories that describe Papyrus as just a secondary side-laugh either, because with the patch it’s heavily implied that it is Papyrus who owns the gaster blasters, and in a normal Pacifist playthrough or Neutral run the Annoying Dog saves you by stealing the blasters, and in a Kill All route Papyrus never uses any attack on you, meaning Sans was likely able to get that Special Attack after you kill Papyrus. And since they are Gaster Blasters, I’m leaning heavily towards Papyrus having been involved with Gaster as well, but something having happened to where everyone and Papyrus have no knowledge at all of a timeline where Gaster was alive [except for possibly Sans?].

I’m also pretty iffy about saying that earthbound is so heavily involved in undertale’s storyline, since it makes much more sense to me, as someone who also makes things, for a creator to just stick homages to past projects in their big ones. For Toby Fox, his earthbound hack was one of his first big projects, and it introduced some of his music, so I can see him referencing star men and other earthbound things but not necessarily basing important chunks of story off of another series entirely that would be crucial to the plot.

So, overall, I think GameTheory missed out on some important details but I laughed a lot at the imagery of Sans just aimlessly floating thru a starry background.

my band direction is really adamant about replacing our contras with sousaphones but im just like????if I wanted to march a fucking steel hula hoop id go to some weak ass school with little weak ass tuba players who dont march the weight of an entire nations sins on their left shoulder

Scientists just achieve quantum teleportation — and proved Einstein wrong

On Thursday, scientists from the Netherlands announced that they were able to achieve quantum teleportation — a feat that Einstein once dismissed as “spooky action at a distance.”

In a new paper published in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology said they were able to “reliably teleport information between two quantum bits separated by three meters, or about 10 feet.” This goes against Einstein’s notion of particle entanglement, and is a huge breakthrough for quantum mechanical theory — and information transmission as we know it.
