Beating three-parameter precision trade-offs with entangling collective measurements
Simon K. Yung, Wen-Zhe Yan, Lan-Tian Feng +10
Quantum-mechanical incompatibility, which precludes the simultaneous precise measurement of non-commuting observables, imposes fundamental limits on the rate at which classical inf…

Squeezing at the normal-mode splitting frequency of a nonlinear coupled cavity
Jonas Junker, Jiayi Qin, Vaishali B. Adya +5
Coupled optical cavities, which support normal modes, play a critical role in optical filtering, sensing, slow-light generation, and quantum state manipulation. Recent theoretical…

Amplified Squeezed States: Analyzing Loss and Phase Noise
K. M. Kwan, M. J. Yap, J. Qin +7
Phase-sensitive amplification of squeezed states is a technique to mitigate high detection loss, e.g. at 2-micrometre wavelengths. Our analytical model of amplified squeezed states…
