Work fluctuations due to partial thermalizations in two-level systems
Maria Quadeer, Kamil Korzekwa, Marco Tomamichel
We study work extraction processes mediated by finite-time interactions with an ambient bath -- \emph{partial thermalizations} -- as continuous time Markov processes for two-level…
Quantum advantage in simulating stochastic processes
Kamil Korzekwa, Matteo Lostaglio
We investigate the problem of simulating classical stochastic processes through quantum dynamics, and present three scenarios where memory or time quantum advantages arise. First,…
Robustness of Noether's principle: Maximal disconnects between conservation laws and symmetries in quantum theory
Cristina Cirstoiu, Kamil Korzekwa, David Jennings
To what extent does Noether's principle apply to quantum channels? Here, we quantify the degree to which imposing a symmetry constraint on quantum channels implies a conservation l…
Distinguishing classically indistinguishable states and channels
Kamil Korzekwa, Stanisław Czachórski, Zbigniew Puchała +1
We investigate an original family of quantum distinguishability problems, where the goal is to perfectly distinguish between quantum states that become identical under a comple…
Avoiding irreversibility: engineering resonant conversions of quantum resources
Kamil Korzekwa, Christopher T. Chubb, Marco Tomamichel
We identify and explore the intriguing property of resource resonance arising within resource theories of entanglement, coherence and thermodynamics. While the theories considered…
Moderate deviation analysis of majorisation-based resource interconversion
Christopher T. Chubb, Marco Tomamichel, Kamil Korzekwa
We consider the problem of interconverting a finite amount of resources within all theories whose single-shot transformation rules are based on a majorisation relation, e.g. the re…
