Dynamical maps, quantum detailed balance and Petz recovery map
Álvaro M. Alhambra, Mischa P. Woods
Markovian master equations (formally known as quantum dynamical semigroups) can be used to describe the evolution of a quantum state when in contact with a memoryless thermal b…
Autonomous quantum clocks: does thermodynamics limit our ability to measure time?
Paul Erker, Mark T. Mitchison, Ralph Silva +3
Time remains one of the least well understood concepts in physics, most notably in quantum mechanics. A central goal is to find the fundamental limits of measuring time. One of the…
Autonomous quantum machines and the finite sized Quasi-Ideal clock
Mischa P. Woods, Ralph Silva, Jonathan Oppenheim
Processes such as quantum computation, or the evolution of quantum cellular automata are typically described by a unitary operation implemented by an external observer. In particul…
Surpassing the Carnot Efficiency by extracting imperfect work
Nelly Huei Ying Ng, Mischa Woods, Stephanie Wehner
A suitable way of quantifying work for microscopic quantum systems has been constantly debated in the field of quantum thermodynamics. One natural approach is to measure the averag…
Realising a quantum absorption refrigerator with an atom-cavity system
Mark T. Mitchison, Marcus Huber, Javier Prior +2
An autonomous quantum thermal machine comprising a trapped atom or ion placed inside an optical cavity is proposed and analysed. Such a machine can operate as a heat engine whose w…
