Experimental observation of spontaneous symmetry breaking in a quantum phase transition
Spontaneous symmetry breaking (SSB) plays a central role in understanding a large variety of phenomena associated with phase transitions, such as superfluid and superconductivity. So far, the transition from a...

Open AccessEntanglement-interference complementarity and experimental demonstration in a superconducting circuit
Quantum entanglement between an interfering particle and a detector for acquiring the which-path information plays a central role for enforcing Bohr’s complementarity principle. However, the quantitative relat...

Criticality-enhanced quantum sensing in the anisotropic quantum Rabi model
Quantum systems that undergo quantum phase transitions exhibit divergent susceptibility and can be exploited as probes to estimate physical parameters. We generalize the dynamic framework for criticality-enhan...
