Quantum Superposition
Have we met? Do we know each other? You say you’ve never seen me before, I must be mistaken. But I’m not so sure, I’m not convinced. I feel as if you and I have met time and time again. Am I mistaken? No, this feeling is far too intense, I can’t be imagining this. I feel, no, I -know- we have spent much time together. The images are so vivid, so profuse; do not tell me you remember nothing, I beg of you. All the words we shared, the hours that passed by as we embraced quietly, reveling in the tenderness of each other’s arms… You remember nothing? Could I be wrong? The memories, so real, so fresh, how could I make this up? A dream, you say? It seems as though that is the only possibility. But so detailed, so perfect, so…real. I… I should go… Goodbye..my love.
Hi I'm a dumbo but
Can someone explain to me what exactly is a quantum superposition and how Cas used that as his advantage? I kinda get that since there’s so many Biggerson’s the angels can’t determine which one Cas ends up being at but is that it? I feel like it should be more complicated than that lol
my favorite thing to think about is the fact that there are billions of universes beside ours, quantum superposition locks us all into our shared observable universe but all possibilities, everything that can happen, everything that could have been, and everything we can’t see still exists. There are an infinite amount of universes and an infinite amount of possibilities. So it is possible to think that somewhere out there, in some universe it is possible that what we call Doctor Who is just life. In some universe our Whoniverse is reality. It is possible that the doctor is out there. And it’s possible to imagine that he could possibly one day find out how to travel into new universes and maybe if we are lucky hel’ll choose ours. Nothing is impossible because literally everything is possible. It could happen, I mean… he is The Doctor afterall.
(Real) Example of Quantum Superposition
- Howard : What are you guys doing here?
- Leonard : When you left, you weren't sure whether or not you wanted to know what was in your dad's letter, so we came up with kind of a cool solution.
- Howard : Oh, yeah, what's that?
- Sheldon : It's simple, really.
- Sheldon : It occurred to me that knowing and not knowing can be achieved by creating a macroscopic example of quantum superposition. The-the principle that a physical system exists partially in all its possible states at once.
- Penny : We were all thinking it, really. It was kind of the elephant in the room, so...
- Sheldon : Anyway, um, I realize if we each present you with an account of what your father wrote to you, only one of which is true, and then we don't tell you which one it is, you will forever be in a state of epistemic ambivalence.
- Penny : Yeah. And I said if it wasn't epistemic, we might as well not do it

Quantum Teleportation
Have you ever dreamed of being present at two places at the same time??? Don’t get surprised by this as with the rate by which technologies are developing this dream will become a reality one day.
Teleportation is a phenomenon in which a beam of an object or a person is shown in another place by replicating its copy. Quantum teleportation is somehow different from simple teleportation and in this technique, two photons are entangled in such a way that if the state of one of them is altered then there will be alteration in the state of other one automatically as if they were connected with each other. Thus the information can be transported from one place to another. Scientists of Japan and Australia have used this technique and made a ‘teleporter’ and a ‘paradoxical cat’ with the help of which they are able to achieve a new breakthrough in communication field. The cat term is used to refer to the ‘wave packets’ of light which represents Schrodinger’s Cat, the famous thought experiment.
Wave packets of light or we can say complex set of quantum information or quantum states have been successfully teleported from one place to another without actual transfer of a particle between them. Actually, a macroscopic beam of light was taken and a quantum superposition is applied on it and is teleported from one place to another. Superposition provides power to quantum computers, and in parallel processing, a same thing needs to be different (like one and zero) at different places.
High fidelity transmission of a large amount of information like quantum encryption keys with a very high speed is now possible through communications networks. The greatest distance covered with the help of this technology is 143 km over the sea stretch which separates two Canary Islands. In simple terms, the information which is present in the form of light has been manipulated by destroying it in one spot and recreating at another place, so that it exists in two places at the same time. This achievement could pave the way for applying this technology between ground stations and the satellites. Thus, near future is coming up with the means of quantum communications applications as its milestone.
