Direct Pseudopotential Calculation of Exciton Coulomb and
... for the exciton ground-state Coulomb energy [21,22] of GaAs quantum dots are compared in Table I. As we can see, the perturbative approach mimics the self-consistent results within 10%, so it is a reasonably good approximation in the size range considered here. The validity of perturbation theory ca ...

Contradiction of Quantum Mechanics with Local Hidden Variables
... eigenvalues of the appropriate system Hermitian operator, which represents the measurement in quantum mechanics, are discrete. In this paper we show how the predictions of quantum mechanics are in disagreement with those of local hidden variable theories for a situation involving continuous quadratu ...

Approximate Quantum Error-Correcting Codes and Secret Sharing
... Secret Sharing and Quantum Error Correction Classically, an (n, d)-secret sharing scheme splits a secret into n pieces so that no d−1 shares reveal any information about the secret, but any d shares allow one to reconstruct it. Such a scheme is already an error-correcting code, since it allows one ...

Closed timelike curves make quantum and classical computing
... Notice that Deutsch’s resolution works just as well in classical probabilistic theories as in quantum-mechanical ones. For just as every quantum operation has a fixed-point, so every Markov chain has a stationary distribution. What matters is simply that the state space and the set of transformation ...
