Kubo-Martin-Schwinger relation for energy eigenstates of SU(2)-symmetric quantum many-body systems
Jae Dong Noh, Aleksander Lasek, Jade LeSchack +1
The fluctuation-dissipation theorem (FDT) is a fundamental result in statistical mechanics. It stipulates that, if perturbed out of equilibrium, a system responds at a rate proport…
Integrability of Goldilocks quantum cellular automata
Logan E. Hillberry, Lorenzo Piroli, Eric Vernier +3
Goldilocks quantum cellular automata (QCA) have been simulated on quantum hardware and produce emergent small-world correlation networks. In Goldilocks QCA, a single-qubit unitary…
Key Issues Review: Useful autonomous quantum machines
José Antonio MarÃn Guzmán, Paul Erker, Simone Gasparinetti +2
Controlled quantum machines have matured significantly. A natural next step is to increasingly grant them autonomy, freeing them from time-dependent external control. For example,…
Complexity-constrained quantum thermodynamics
Anthony Munson, Naga Bhavya Teja Kothakonda, Jonas Haferkamp +3
Quantum complexity measures the difficulty of realizing a quantum process, such as preparing a state or implementing a unitary. We present an approach to quantifying the thermodyna…
Thermally driven quantum refrigerator autonomously resets superconducting qubit
Mohammed Ali Aamir, Paul Jamet Suria, José Antonio MarÃn Guzmán +4
Although classical thermal machines power industries and modern living, quantum thermal engines have yet to prove their utility. Here, we demonstrate a useful quantum absorption re…
Quantum thermodynamics of nonequilibrium processes in lattice gauge theories
Zohreh Davoudi, Christopher Jarzynski, Niklas Mueller +3
A key objective in nuclear and high-energy physics is to describe nonequilibrium dynamics of matter, e.g., in the early universe and in particle colliders, starting from the Standa…
