Entanglement generation and multiparticle interferometry with neutral atoms
Artem M. Dudarev, Roberto B. Diener, Biao Wu +2
We study the preparation and manipulation of states involving a small number of interacting particles. By controlling the splitting and fusing of potential wells, we show how to in…
Explicit Solution of the Time Evolution of the Wigner Function
Cheuk-Yin Wong
Previously, an explicit solution for the time evolution of the Wigner function was presented in terms of auxiliary phase space coordinates which obey simple equations that are anal…
Experimental Entanglement Concentration and Universal Bell-state Synthesizer
Yoon-Ho Kim, Sergei P. Kulik, Maria V. Chekhova +2
We report a novel Bell-state synthesizer in which an interferometric entanglement concentration scheme is used. An initially mixed polarization state from type-II spontaneous param…
Generation of Pulsed Polarization Entangled Two-Photon State via Temporal and Spectral Engineering
Yoon-Ho Kim, Warren P. Grice
The quantum state of the photon pair generated from type-II spontaneous parametric down-conversion pumped by a ultrafast laser pulse exhibits strong decoherence in its polarization…
Adiabatic Theory of Nonlinear Evolution of Quantum States
Jie Liu, Biao Wu, Qian Niu
We present a general theory for adiabatic evolution of quantum states as governed by the nonlinear Schrodinger equation, and provide examples of applications with a nonlinear tunne…
New summing algorithm using ensemble computing
C. D'Helon, V. Protopopescu
We propose an ensemble algorithm, which provides a new approach for evaluating and summing up a set of function samples. The proposed algorithm is not a quantum algorithm, insofar…
