Stabilizing quantum dynamics through coupling to a quantized environment
Meenu Kumari, Eduardo Martin-Martinez, Achim Kempf +1
We show that introducing a small uncertainty in the parameters of quantum systems can make the dynamics of these systems robust against perturbations. Concretely, for the case wher…
Light, matter, and quantum randomness generation: A relativistic quantum information perspective
Richard Lopp, Eduardo Martin-Martinez
We study how quantum randomness generation based on unbiased measurements on a hydrogen-like atom can get compromised by virtue of the unavoidable coupling of the atom with the ele…
Finite sizes and smooth cutoffs in superconducting circuits
Emma McKay, Adrian Lupascu, Eduardo Martin-Martinez
We investigate the validity of two common assumptions in the modelling of superconducting circuits: first, that the superconducting qubits are pointlike, and second, that the UV be…
A classification of open Gaussian dynamics
Daniel Grimmer, Eric Brown, Achim Kempf +2
We introduce a classification scheme for the generators of bosonic open Gaussian dynamics, providing instructive diagrams description for each type of dynamics. Using this classifi…
Transmitting qubits through relativistic fields
Robert H. Jonsson, Katja Ried, Eduardo Martin-Martinez +1
Wireless communication derives its power from the simultaneous emission of signals in multiple directions. However, in the context of quantum communication, this phenomenon must be…
Transmission of Information in Non-Local Field Theories
Alessio Belenchia, Dionigi M. T. Benincasa, Stefano Liberati +1
The signaling between two observers in 3+1 dimensional flat spacetime coupled locally to a non-local field is considered. We show that in the case where two observers are purely ti…
