Entanglement-Assisted Timing Optimization for Discriminating Amplitude-Damping Dynamics
Massimiliano F. Sacchi, Milajiguli Rexiti, Stefano Mancini
We analyze minimum-error discrimination of two qubit dynamical processes generated by phase-covariant amplitude-damping Lindbladians in a single-use scenario. The optimization invo…

Bayesian and Markovian classical feedforward for discriminating qubit channels
Milajiguli Rexiti, Stefano Mancini
We address the issue of multishot discrimination between two qubit channels by invoking a simple adaptive protocol that employs Helstrom measurement at each step and classical info…

Discrimination of bosonic dephasing quantum channels
Samad Khabbazi Oskouei, Laleh Memarzadeh, Milajiguli Rexiti +1
We study the possibility of discriminating between two bosonic dephasing quantum channels. We show that unambiguous discrimination is not realizable. We then consider discriminatio…
