Impact of quadrature measurement on quantum coherence
LucÃa Ãlvarez, Alfredo Luis
We examine the behavior of quadrature coherence under the measurement of the same field quadrature. This is carried out with the help of a beam splitter, which implies the contribu…
Generalized measurements for Bell tests in different probability spaces
Alfredo Luis
Bell tests are of profound statistical nature. Besides physical considerations, the proper understanding of their implications should involve detailed statistical analyses. In this…
Statistical analysis of Bell tests via generalized measurements
Alfredo Luis
We provide a fully statistical analysis of the results of a Bell test beyond mean values. This is possible in a practical scheme where all the observables involved in the test are…
Single-measurement Bell analysis
Alfredo Luis
We examine the satisfaction of Bell criteria for single realizations of quantum systems. This is possible via the joint noisy measurement of all observables involved in the Bell te…
