Noise Resilience of Quantum Key Distribution Protocols Secured Against Independent Attacks With One-Way Communication
Adam Bílek, Ryszard Kukulski, Paulina Lewandowska +2
We investigate the resilience to noise of single-qubit quantum key distribution (QKD) protocols in the scenario of security against independent eavesdropping attacks and key distil…
Asymptotic distinguishability of Haar-averaged measurement models
Ludmiła Marcinkowska, Łukasz Pawela, Marcin Markiewicz +1
We study discrimination problems generated by the same basic Haar-random measurement mechanism at two observational levels. First, we derive an explicit expression for the type-II…
IntegrateUnitary.jl: A Julia package for symbolic integration over Haar measures
Łukasz Pawela, Zbigniew Puchała
Symbolic integration over the Haar measure of compact groups is a computational cornerstone in quantum information science and random matrix theory. We present \texttt{IntegrateUni…
Choi-level twirling of quantum channels: finite constructions and non-compact transformations
Marcin Markiewicz, Łukasz Pawela, Zbigniew Puchała
Twirling, i.e. averaging over symmetry actions, is a standard tool for reducing quantum states and channels to a symmetry-invariant form. We study channel twirling from the perspec…
Single-shot comparison of random quantum channels and measurements
Marcin Markiewicz, Łukasz Pawela, Zbigniew Puchała
In this work we provide an efficiency analysis of the problem of comparison of two randomly chosen quantum operations in the single-shot regime. We provide tight bounds for the suc…
Local certification of unitary operations
Ryszard Kukulski, Mateusz Stępniak, Kamil Hendzel +3
In this work, we analyze the local certification of unitary quantum channels, which is a natural extension of quantum hypothesis testing. A particular case of a quantum channel ope…
