Divergence-free approach for obtaining decompositions of quantum-optical processes

K. K. Sabapathy, J. S. Ivan, R. García-Patrón +1

Operator-sum representations of quantum channels can be obtained by applying the channel to one subsystem of a maximally entangled state and deploying the channel-state isomorphism…

Scaling maps of $s$ -ordered quasiprobabilities are either nonpositive or completely positive

J. Solomon Ivan, Krishna Kumar Sabapathy, R. Simon

Continuous-variable systems in quantum theory can be fully described through any one of the $s$ -ordered family of quasiprobabilities $Λ_{s} (α)$ , $s \in [- 1, 1]$ . We…
