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…
Violation of the two-time Leggett-Garg inequalities for a coarse-grained quantum field
Masaki Tani, Kosei Hatakeyama, Daisuke Miki +2
We investigate the violation of the Leggett-Garg inequalities for a quantum field, focusing on the two-time quasi-probability distribution function of the dichotomic variable with…
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…
Violation of the two-time Leggett-Garg inequalities for a harmonic oscillator
Kosei Hatakeyama, Daisuke Miki, Masaki Tani +5
We investigate the violation of the Leggett-Garg inequalities for a harmonic oscillator in various quantum states. We focus on the two-time quasi-probability distribution function…
