Emerging Non-Hermitian Topology in a Chiral Driven-Dissipative Bose-Hubbard Model
Laszlo Rassaert, Tomás Ramos, Tommaso Roscilde +1
We introduce a driven-dissipative Bose-Hubbard chain describing coupled lossy photonic modes, in which time-reversal symmetry is broken by a coherent drive with a uniform phase gra…
Symmetry: a fundamental resource for quantum coherence and metrology
Irénée Frérot, Tommaso Roscilde
We introduce a new paradigm for the preparation of deeply entangled states useful for quantum metrology. We show that when the quantum state is an eigenstate of an operator , ob…
Scalable spin squeezing from critical slowing down in short-range interacting systems
Tommaso Roscilde, Filippo Caleca, Adriano Angelone +1
Long-range spin-spin interactions are known to generate non-equilibrium dynamics which can squeeze the collective spin of a quantum spin ensemble in a scalable manner, leading to s…
Quantum correlations in the steady state of light-emitter ensembles from perturbation theory
Dolf Huybrechts, Tommaso Roscilde
The coupling of a quantum system to an environment leads generally to decoherence, and it is detrimental to quantum correlations within the system itself. Yet some forms of quantum…
Quantum degeneracy and spin entanglement in ideal quantum gases
Fatma Zouari Ahmed, Mohammed Tayeb Meftah, Tommaso Roscilde
Quantum degeneracy is the central many-body feature of ideal quantum gases stemming from quantum mechanics. In this work we address its relationship to the most fundamental form of…
