Generalizing Choi map in beyond circulant scenario
Anindita Bera, Giovanni Scala, Gniewomir Sarbicki +1
We present a generalization of the family of linear positive maps in proposed thirty years ago by Cho et al. (Linear Algebra Appl. , 213 (1992)) as a generalizatio…
Synchronized Bell protocol for detecting non-locality between modes of light
Madhura Ghosh Dastidar, Gniewomir Sarbicki, Vidya Praveen Bhallamudi
In the following paper, we discuss a possible detection of non-locality in two-mode light states in the Bell protocol, where the local observables are constructed using displacemen…
A class of optimal positive maps in
Anindita Bera, Gniewomir Sarbicki, Dariusz Chruściński
It is proven that a certain class of positive maps in the matrix algebra consists of optimal maps, i.e. maps from which one cannot subtract any completely positive map withou…
Detecting Entanglement Between Modes of Light
Madhura Ghosh Dastidar, Gniewomir Sarbicki
We consider a subgroup of unitary transformations on a mode of light induced by a Mach-Zehnder Interferometer and an algebra of observables describing a photon-number detector proc…
