Entanglement-assisted Orientation in Space
Caslav Brukner, Nikola Paunkovic, Terry Rudolph +1
We demonstrate that quantum entanglement can help separated individuals in making decisions if their goal is to find each other in the absence of any communication between them. We…
Quantum noise and stochastic reduction
Dorje C. Brody, Lane P. Hughston
In standard nonrelativistic quantum mechanics the expectation of the energy is a conserved quantity. It is possible to extend the dynamical law associated with the evolution of a q…
Solvable model of quantum microcanonical states
Carl M Bender, Dorje C Brody, Daniel W Hook
This letter examines the consequences of a recently proposed modification of the postulate of equal {\it a priori} probability in quantum statistical mechanics. This modification,…
Microcanonical distributions for quantum systems
Dorje C Brody, Daniel W Hook, Lane P Hughston
The standard assumption for the equilibrium microcanonical state in quantum mechanics, that the system must be in one of the energy eigenstates, is weakened so as to allow superpos…
Increasing identical particle entanglement by fuzzy measurements
D. Cavalcanti, M. F. Santos, M. O. Terra Cunha +2
We investigate the effects of fuzzy measurements on spin entanglement for identical particles, both fermions and bosons. We first consider an ideal measurement apparatus and define…
Cooling many particles to very low temperatures
Almut Beige, Peter L. Knight, Giuseppe Vitiello
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently using a bichromatic interaction. The…
