Using a series of quantum correlated photon pairs, we propose a theoretical scheme for any-to-any multi-user quantum key distribution network based on different
Effect of laser fields on Na2 interaction potentials is studied by calculating the time-resolved photoelectron spectrum (TRPES) with the time-dependent wave-pac
In a recent paper, Sacchi (Phys. Rev. Lett. 96 (2006) 220502) studied the information-disturbance tradeoff in estimating an unknown two-qubit maximally entangle
The dynamics of the dc and ac driving Josephson junction equation is studied in terms of the tvo-dimensional Poincaré map. The smooth invariant circle on the p
A method for the control of chaos in the current-mode boost converter is presented by using the first-order dynamic feedback control. The feedback part consists
