Tomography of a Macroscopic Quantum State influenced by Classical Self-Gravity
Wenjie Zhong, Yubao Liu, Yanbei Chen +2
Macroscopic optomechanical systems offer a promising testbed for distinguishing whether gravity acts as a quantum interaction or as a classical field. Schrodinger-Newton (SN) theor…
Optimized Quantum States for Sensing in the Presence of Loss and Phase Noise
Shruti Maliakal, Zachary Mann, Christopher Wipf +3
Squeezed vacuum lets gravitational-wave detectors and other quantum sensors surpass the standard quantum limit, and is optimal in the loss-limited regime; phase noise breaks this o…
Gaussian Quantum Metrology with Realistic Linear Sensors
Jacques Ding, James W. Gardner, Tuvia Gefen +1
Quantum sensing promises enhanced precision, but the usual quantum Cramer Rao bound can be too optimistic for realistic linear sensors, where squeezing, filtering, and loss reshape…
Amplification and generation bounds of gravity-induced entanglement in pulsed optomechanical systems
Daisuke Miki, Alfred Li, Yanbei Chen
We investigate gravity-induced entanglement between the output optical fields of two red-detuned pulsed optomechanical systems with their masses coupled by mutual gravitational int…
Universal Bound for Entanglement Generation
Alfred Li, Daisuke Miki, Yanbei Chen
We derive a universal condition for entanglement generation under general bilinear interactions in the presence of white thermal noise. While various protocols have been proposed t…
Towards sample-optimal learning of bosonic Gaussian quantum states
Senrui Chen, Francesco Anna Mele, Marco Fanizza +5
Continuous-variable systems enable key quantum technologies in computation, communication, and sensing. Bosonic Gaussian states emerge naturally in various such applications, inclu…
