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…
Implementation and topological characterization of Weyl exceptional rings in quantum-mechanical systems
Hao-Long Zhang, Pei-Rong Han, Xue-Jia Yu +8
Non-Hermiticity can lead to the emergence of many intriguing phenomena that are absent in Hermitian systems, enabled by exceptional topological defects, among which Weyl exceptiona…
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…
Characterization of non-Markovianity with maximal extractable qubit-reservoir entanglement
Pei-Rong Han, Fan Wu, Xin-Jie Huang +5
Understanding the dynamical behavior of a qubit in a reservoir is critical to applications in quantum technological protocols, ranging from quantum computation to quantum metrology…
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…
Non-adiabatic holonomic quantum operations in continuous variable systems
Hao-Long Zhang, Yi-Hao Kang, Fan Wu +2
Quantum operations by utilizing the underlying geometric phases produced in physical systems are favoured due to its potential robustness. When a system in a non-degenerate eigenst…
