Deadpool returns to Earth after taking over Macho Gomez’s bounty hunting job last issue, to find himself face to face with everyone who wants to kill him. Again. And then, Deadpool tries to provoke The Hulk into killing him! I won’t be reading the classic, since I’ve read it before, and I don’t fancy it again right now.
do I like them: Every quirk of his green brow gives me warm fuzzles.
5 good qualities: loyal, can speak whale, “This simple feeling,” misuses colorful metaphors, “Difficult to be precise, Captain. I should say approximately 7,824.7 to 1′”
3 bad qualities: odd fashion sense, Pon Farr, stubborn
favourite episode/etc: While “City on the Edge of Forever” is my fav TOS episode, a more Spock-specific fav would be “The Devil in the Dark” or “Operation: Annihilate”
ot3: Kirk/Spock/too many tribbles

best quote: “They are not the hell your whales”
head canon: one day finally gives in to the inevitable and gets a cat. and then another. and then another. mccoy is horrified by all the allergens coming in and out. kirk refers to them as The Children and gives them each a trust fund

[ Abstract ]
We introduce quantum optical dipole radiation fields defined in terms of photon creation and annihilation operators. These fields are identified through their spatial dependence, as the components of the total fields that survive infinitely far from the dipole source. We use these radiation fields to perturbatively evaluate the electromagnetic radiated energy-flux of the excited dipole. Our results indicate that the standard interpretation of a bare atom surrounded by a localised virtual photon cloud, is difficult to sustain, because the radiated energy-flux surviving infinitely far from the source contains virtual contributions. It follows that there is a clear distinction to be made between a radiative photon defined in terms of the radiation fields, and a real photon, whose identification depends on whether or not a given process conserves the free energy. This free energy is represented by the difference between the total dipole-field Hamiltonian and its interaction component.

We construct a new class of quantum error-correcting codes for a bosonic mode which are advantageous for applications in quantum memories, communication, and scalable computation. These `binomial quantum codes’ are formed from a finite superposition of Fock states weighted with binomial coefficients. The binomial codes can exactly correct errors that are polynomial up to a specific degree in bosonic creation and annihilation operators, including amplitude damping and displacement noise as well as boson addition and dephasing errors. For realistic continuous-time dissipative evolution, the codes can perform approximate quantum error correction to any given order in the timestep between error detection measurements. We present an explicit approximate quantum error recovery operation based on projective measurements and unitary operations. The binomial codes are tailored for detecting boson loss and gain errors by means of measurements of the generalized number parity. We discuss optimization of the binomial codes and demonstrate that by relaxing the parity structure, codes with even lower unrecoverable error rates can be achieved. The binomial codes are related to existing two-mode bosonic codes but offer the advantage of requiring only a single bosonic mode to correct amplitude damping as well as the ability to correct other errors. Our codes are similar in spirit to `cat codes’ based on superpositions of the coherent states, but offer several advantages such as smaller mean number, exact rather than approximate orthonormality of the code words, and an explicit unitary operation for repumping energy into the bosonic mode. The binomial quantum codes are realizable with current superconducting circuit technology and they should prove useful in other quantum technologies, including bosonic quantum memories, photonic quantum communication, and optical-to-microwave up- and down-conversion.
