Quantum Brachistochrone for Mixed States

A. Carlini, A. Hosoya, T. Koike +1

We present a general formalism based on the variational principle for finding the time-optimal quantum evolution of mixed states governed by a master equation, when the Hamiltonian…

Quantum Entropy Bound by Information in Black Hole Spacetime

A. Hosoya, A. Carlini

We show that the increase of the generalized entropy by a quantum process outside the horizon of a black hole is more than the Holevo bound of the classical information lost into t…

Quantum Computers and Unstructured Search: Finding and Counting Items with an Arbitrarily Entangled Initial State

A. Carlini, A. Hosoya

Grover's quantum algorithm for an unstructured search problem and the Count algorithm by Brassard et al. are generalized to the case when the initial state is arbitrarily and maxim…

Quantum Probabilistic Subroutines and Problems in Number Theory

A. Carlini, A. Hosoya

We present a quantum version of the classical probabilistic algorithms aˋ la Rabin. The quantum algorithm is based on the essential use of Grover's operator for the quantu…
