Closed timelike curves make quantum and classical computing equivalent
... clear and consistent. And at a purely mathematical level, Deutsch’s causal consistency account of CTCs is the clearest we have seen. Although CTCs need not lead to inconsistencies, Deutsch pointed out that they would have striking consequences for the theory of computing. As an example, CTCs could b ...

Quantum Mechanics II SS 2014
... In the special case of a central potential, V (r), the orbital angular momentum, L, particle is a constant of motion. Therefore, there exist stationary states with well-defined ~ 2 and Lz . And, as we found in angular momentum, i.e., eigenstates common to H, L QM I, the Schrödinger equation of a sp ...

By ruling out local hidden variables, Bell demolished Einstein’s dream that the indeterminacy of quantum theory could be eradicated by adopting a more complete, yet still local, description of Nature. If we accept locality as an inviolable principle, then we are forced to accept r ...

Description of quantum coherence in thermodynamic
... One might therefore think that the unitary group generated by the free Hamiltonian H of the system should not play any particular role. However, this is not the case, and from a perspective of asymmetry we find that: Theorem 1: The set of thermal operations on a quantum system is a strict subset of t ...

... then the only possible choice is p(v) = |v|w|2 for all vectors v and an arbitrary but fixed vector w, provided that probabilities are assumed to be non-contextual. The normalization requirement of Eq. (1) for p(v) with respect to any orthonormal basis can be physically motivated by remembering that ...
