The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

Present protocols of criticality-enhanced sensing with open quantum sensors assume direct
measurement of the sensor and omit the radiation quanta emitted to the environment …

Superradiant phase transitions (SPTs) are important for understanding light-matter
interactions at the quantum level, and play a central role in criticality-enhanced quantum …

We compare critical quantum sensing to passive quantum strategies to perform frequency
estimation, in the case of single-mode quadratic Hamiltonians. We show that, while in the …

Critical metrology relies on the precise preparation of a system in its ground state near a
quantum phase transition point where quantum correlations get very strong. Typically, this …

Autonomous quantum error correction (AQEC) protects logical qubits by engineered
dissipation and thus circumvents the necessity of frequent, error-prone measurement …

We demonstrate the emergence of nonreciprocal superradiant phase transitions and novel
multicriticality in a cavity quantum electrodynamics system, where a two-level atom interacts …

Quantum simulation provides important tools in studying strongly correlated many-body
systems with controllable parameters. As a hybrid of two fundamental models in quantum …

The superradiant phase transition in thermal equilibrium is a fundamental concept bridging
statistical physics and electrodynamics, which has never been observed in real physical …
