Emergence of irreversible decoherence from unitary dynamics
Ri-Hua Zheng, Jia-Hao Lü, Fan Wu +4
The decoherence of superpositions of classically distinguishable states (cat states) is crucial for understanding quantum-to-classical transitions and quantum measurements. So far,…
Observation of photonic dynamics in dissipative quantum Rabi models
Wen Ning, Ri-Hua Zheng, Jia-Hao Lü +5
The quantum Rabi model (QRM), composed of a qubit interacting with a quantized photonic field, is a cornerstone of quantum optics. The QRM with dominant unitary dynamics has been d…
Experimental demonstration of spontaneous symmetry breaking with emergent multi-qubit entanglement
Ri-Hua Zheng, Wen Ning, Jia-Hao Lü +8
Spontaneous symmetry breaking (SSB) is crucial to the occurrence of phase transitions. Once a phase transition occurs, a quantum system presents degenerate eigenstates that lack th…
Experimental observation of spontaneous symmetry breaking in a quantum phase transition
Wen Ning, Ri-Hua Zheng, Jia-Hao Lü +3
Spontaneous symmetry breaking (SSB) plays a central role in understanding a large variety of phenomena associated with phase transitions, such as superfluid and superconductivity.…
Critical quantum metrology robust against dissipation and non-adiabaticity
Jia-Hao Lü, Wen Ning, Fan Wu +6
Critical systems near quantum phase transitions were predicted to be useful for improvement of metrological precision, thanks to their ultra-sensitive response to a tiny variation…
Measuring topological invariants for higher-order exceptional points in quantum three-mode systems
Pei-Rong Han, Wen Ning, Xin-Jie Huang +7
Owing to the presence of exceptional points (EPs), non-Hermitian (NH) systems can display intriguing topological phenomena without Hermitian analogs. However, experimental characte…
