Transmission of quantum information through quantum fields
Petar Simidzija, Aida Ahmadzadegan, Achim Kempf +1
We investigate the quantum channel consisting of two localized quantum systems that communicate through a scalar quantum field. We choose a scalar field rather than a tensor or vec…
Faster-than-light signalling in the rotating-wave approximation
Nicholas Funai, Eduardo Martin-Martinez
We present new results on the causality violations introduced by the rotating wave approximation commonly used in quantum optics and high-energy physics. We find that the causality…
Zeno Friction and Anti-friction from Quantum Collision Models
Daniel Grimmer, Achim Kempf, Robert B. Mann +1
We analyze the quantum mechanics of the friction experienced by a small system as it moves non-destructively with velocity over a surface. Specifically, we model the interactio…
Work distributions on quantum fields
Alvaro Ortega, Emma McKay, Álvaro M. Alhambra +1
We study the work cost of processes in quantum fields without the need of projective measurements, which are always ill defined in quantum field theory. Inspired by interferometry…
Fundamental limitations to local energy extraction in quantum systems
Álvaro M. Alhambra, Georgios Styliaris, Nayeli A. Rodriguez-Briones +2
We examine when it is possible to locally extract energy from a bipartite quantum system in the presence of strong coupling and entanglement, a task which is expected to be restric…
A classification of Markovian fermionic Gaussian master equations
Marvellous Onuma-Kalu, Daniel Grimmer, Robert B. Mann +1
We introduce a classification scheme for the generators of open fermionic Gaussian dynamics. We simultaneously partition the dynamics along the following four lines: (1) unitary ve…
