... which roughly reduces to ð1 tÞ2 for small transmission efficiency. As can be seen from Eqs. (2) and (3), there is a trade-off on the transmission coefficient t of the partial beam splitter. The amplification of the entangled component favors t 1, whereas a high success probability favors t 0. ...

(More technically, when does the actual quantum state stop being a linear combination of states, each of which resemble different classical states, ...

Moreover, non-symmetric states are impossible in the quantum case (that is, analogues of C3 and C4 for quantum particles are never realised). This ...

... 7. Explain why the quantum Hall effect is robust. The quantum Hall effect is robust because it exists so long as there are edge states at opposite sides of the sample, which carry current in one direction only and are in separate equilibrium. The states on a single edge are chiral, that is, they pro ...

Why the Logical Disjunction in Quantum Logic is Not
... We put forward a physical explanation of why, in quantum logic, the logical disjunction does not behave classically, even for compatible propositions. Most studies of quantum logic have concentrated on the algebraic structure of the set of propositions, trying to identify the structural differences ...
