Perfect quantum protractors
Michał Piotrak, Marek Kopciuch, Arash Dezhang Fard +3
In this paper we introduce and investigate the concept of a perfect quantum protractor, a pure quantum state that generates three different orthogonal bas…
Improved simulation of quantum circuits dominated by free fermionic operations
Oliver Reardon-Smith, Michał Oszmaniec, Kamil Korzekwa
We present a classical algorithm for simulating universal quantum circuits composed of "free" nearest-neighbour matchgates or equivalently fermionic-linear-optical (FLO) gates, and…
Quantum-embeddable stochastic matrices
Fereshte Shahbeigi, Christopher T. Chubb, Ryszard Kukulski +2
The classical embeddability problem asks whether a given stochastic matrix , describing transition probabilities of a -level system, can arise from the underlying homogeneous…
Resource engines
Hanna Wojewódka-Ściążko, Zbigniew Puchała, Kamil Korzekwa
In this paper we aim to push the analogy between thermodynamics and quantum resource theories one step further. Previous inspirations were based predominantly on thermodynamic cons…
Thermal recall: Memory-assisted Markovian thermal processes
Jakub Czartowski, A. de Oliveira Junior, Kamil Korzekwa
We develop a resource-theoretic framework that allows one to bridge the gap between two approaches to quantum thermodynamics based on Markovian thermal processes (which model memor…
Quantum dichotomies and coherent thermodynamics beyond first-order asymptotics
Patryk Lipka-Bartosik, Christopher T. Chubb, Joseph M. Renes +2
We address the problem of exact and approximate transformation of quantum dichotomies in the asymptotic regime, i.e., the existence of a quantum channel mapping $ρ_1^{…
