Quantum Sensing Beyond Exceptional Points via Hidden symmetry-protected vacuum-noise fixed point
Wencong Wang, Yuyang Liang, Peng Han +3
Exceptional-point (EP) sensing has attracted considerable interest because of its anomalous response scaling. However, recent studies have shown that the enhanced response near an…
Squeezing and Entanglement Dynamics in Phase-Sensitive Non-Hermitian Systems
Ruicong Huang, Wencong Wang, Yuyang Liang +2
Over the past decade, parity-time (PT) symmetry and anti-PT (APT) symmetry in various physical systems have been extensively studied, leading to significant experimental and theore…
Dual opposing quadrature-PT symmetry
Wencong Wang, Jacob Kokinda, Jiazhen Li +3
Our recent research on type-I quadrature parity-time (PT) symmetry, utilizing an open twin-beam system, not only enables observing genuine quantum photonic PT symmetry amid phase-s…
Quadrature-PT symmetry: Classical-to-quantum transition in noise fluctuations
Wencong Wang, Yanhua Zhai, Dongmei Liu +3
While gain-loss-coupled photonic platforms have achieved significant success in studying classical parity-time (PT) symmetry, they encounter challenges in demonstrating pure quantu…
