Infinite Dimensional Asymmetric Quantum Channel Discrimination

Bjarne Bergh, Jan Kochanowski, Robert Salzmann +1

We study asymmetric binary channel discrimination, for qantum channels acting on separable Hilbert spaces. We establish quantum Stein's lemma for channels for both adaptive and par…

Composite Classical and Quantum Channel Discrimination

Bjarne Bergh, Nilanjana Datta, Robert Salzmann

We study the problem of binary composite channel discrimination in the asymmetric setting, where the hypotheses are given by fairly arbitrary sets of channels, and samples do not h…

Classical shadow tomography for continuous variables quantum systems

Simon Becker, Nilanjana Datta, Ludovico Lami +1

In this article we develop a continuous variable (CV) shadow tomography scheme with wide ranging applications in quantum optics. Our work is motivated by the increasing experimenta…

Fully undistillable quantum states are separable

Satvik Singh, Nilanjana Datta

Assume that Alice, Bob, and Charlie share a tripartite pure state . We prove that if Alice cannot distill entanglement with either Bob or Charlie using $|ψ_{ABC}\r…

Ergodic theory of diagonal orthogonal covariant quantum channels

Satvik Singh, Nilanjana Datta, Ion Nechita

We analyze the ergodic properties of quantum channels that are covariant with respect to diagonal orthogonal transformations. We prove that the ergodic behaviour of a channel in th…

Parallelization of Adaptive Quantum Channel Discrimination in the Non-Asymptotic Regime

Bjarne Bergh, Nilanjana Datta, Robert Salzmann +1

We investigate the performance of parallel and adaptive quantum channel discrimination strategies for a finite number of channel uses. It has recently been shown that, in the asymm…
