QUANTUM COMPUTING: AN OVERVIEW
... Quantum computing and quantum information processing are emerging disciplines in which the principles of quantum physics are employed to store and process information. We use the classical digital technology at almost every moment in our lives: computers, mobile phones, mp3 players, just to name a f ...

... here as well for the 2π decay, so we must require the two outgoing pions couple to isospin Itot = 1. But the ω, unlike the ρ, is an isospin-0 particle, so the decay ω 0 → π π (for either charged or neutral pions) has I = 0 in the initial state and must have I = 1 in the final state ⇒ can’t proceed. ...

... Lasers, light-emitting diodes, and incandescent sources all produce light beams that are in Glauber coherent states or their classically-random mixtures.6 In photodetection analyses these quantum states are said to be classical, because their quantum-photodetection statistics agree exactly with thos ...

... Standing in stark contrast to these physical requirements are the conditions that exist in and around animal brains. Brains are warm, wet, biological constructs, honed by evolution to exhibit the sort of robustness and durability needed for survival in the world. Although to some extent they are pro ...

Now, how many times will we need to repeat this adaptive procedure before, given E1 , . . . , Er drawn as above, we can estimate (with high probability) the conditional probability that f (z1 , . . . , zr ) = 1? If we simply apply Theorem 1.1 to the tensor product of all r registers, then it is eas ...

... Second, we note that for the case without a which-way marker, Eq. 共2兲 is equivalent to the uncertainty relations for ⌬ x ⌬ y and ⌬ y ⌬ z , Eqs. 共12兲 and 共13兲. This equivalence can be read in both directions: In one direction, as discussed above, the uncertainty relation implies Eq. 共2兲. In t ...
