Quantum reflection and dwell times of metastable states
Neelima G. Kelkar
The concept of phase and dwell times used in tunneling is extended to quantum collisions to derive a relation between the phase and dwell time delays in scattering. This relation c…
Entanglement, weak values, and the precise inference of joint measurement outcomes for non-commuting observable pairs
Alonso Botero
The problem of inferring the outcome of a simultaneous measurement of two non-commuting observables is addressed. We show that for certain pairs with dense spectra, precise inferen…
Generalized concurrence and limits of separability for two qutrits
César Herreño-Fierro, J. R. Luthra
We present an extension of the Wootters concurrence for the case of two qutrits in mixed states. The reduction of our extension to the case of two levels shows complete agreement w…
Quantum Averages of Weak Values
Yakir Aharonov, Alonso Botero
We re-examine the status of the weak value of a quantum mechanical observable as an objective physical concept, addressing its physical interpretation and general domain of applica…
Spatial structures and localization of vacuum entanglement in the linear harmonic chain
Alonso Botero, Benni Reznik
We study the structure of vacuum entanglement for two complimentary segments of a linear harmonic chain, applying the modewise decomposition of entangled gaussian states discussed…
Quantum coherence, correlated noise and Parrondo games
Chiu Fan Lee, Neil F. Johnson, Ferney Rodriguez +1
We discuss the effect of correlated noise on the robustness of quantum coherent phenomena. First we consider a simple, toy model to illustrate the effect of such correlations on th…
