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 Refrigerator in a Circuit-QED Architecture Based on a Josephson Junction
Patrick P. Hofer, Martí Perarnau-Llobet, Jonatan Bohr Brask +3
An implementation of a small quantum absorption refrigerator in a circuit QED architecture is proposed. The setup consists of three harmonic oscillators coupled to a Josephson unct…
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…
Performance of autonomous quantum thermal machines: Hilbert space dimension as a thermodynamic resource
Ralph Silva, Gonzalo Manzano, Paul Skrzypczyk +1
Multilevel autonomous quantum thermal machines are discussed. In particular, we explore the relation between the size of the machine (captured by Hilbert space dimension), and the…
