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…
