Negativity volume of the generalized Wigner function in gravitating hybrid system
Daisuke Miki, Akira Matsumura, Kazuhiro Yamamoto
We evaluate the gravity-induced negativity volume of the generalized Wigner function in a hybrid system consisting of a particle in a two-localized superposition state and an oscil…

Quantum signature of gravity in optomechanical systems with conditional measurement
Daisuke Miki, Akira Matsumura, Kazuhiro Yamamoto
We investigate the quantum signature of gravity in optomechanical systems under quantum control. We analyze the gravity-induced entanglement and squeezing in mechanical mirrors in…
