Non-Markovian exceptional points in waveguide quantum electrodynamics
Stefano Longhi
Spontaneous emission of a quantum emitter, such as an excited atom, is a fundamental process in quantum electrodynamics (QED), typically associated with exponential decay to the gr…
Quantum key distribution over a metropolitan network using an integrated photonics based prototype
Maria Ana Pereira, Giulio Gualandi, Rebecka Sax +5
An industrial-scale adoption of Quantum Key Distribution (QKD) requires the development of practical, stable, resilient and cost-effective hardware that can be manufactured at larg…
Quantum Pontus-Mpemba Effect Enabled by the Liouvillian Skin Effect
Stefano Longhi
We unveil a quantum Pontus-Mpemba effect enabled by the Liouvillian skin effect in a dissipative tight-binding chain with asymmetric incoherent hopping and coherent boundary coupli…
Exact dynamics and bound states of a cavity coupled to a two-dimensional reservoir
Heng-Na Xiong, Da-Wei Ye, Yang Yang +4
We demonstrate a robust scheme for quantum information storage based on bound states in a two-dimensional coupled-cavity array. When a target cavity is tuned to resonance with the…
Magnetic Control of the Non-Hermitian Skin Effect in Two-Dimensional Lattices
Stefano Longhi
The non-Hermitian skin effect (NHSE) -- the anomalous boundary accumulation of an extensive number of bulk modes -- has emerged as a hallmark of non-Hermitian physics, with broad i…
On entropy production of repeated quantum measurements III. Quantum detailed balance
Tristan Benoist, Noé Cuneo, Vojkan Jakšić +1
In light of the dynamical-systems approach to entropy production in repeated quantum measurements, proposed and illustrated in Commun. Math. Phys. 357, 77-123 (2018) [arXiv:1607.00…
