Testing the quantum nature of gravity through interferometry
Yubao Liu, Yanbei Chen, Kentaro Somiya +1
We propose a Michelson-type interferometric protocol for testing the quantum nature of gravity through testing the phenomenology of semi-classical gravity theory, which predicts a…

Quantum Back Action Evasion with Reservoir Engineering
Yohei Nishino, James W. Gardner, Yanbei Chen +1
We propose a back-action evading scheme for a free mass that combines reservoir engineering with velocity measurement. The underlying principle follows the double-pass-type speed m…

Teleportation-based Speed Meter for Precision Measurement
Yohei Nishino, James W. Gardner, Yanbei Chen +1
We propose a quantum teleportation-based speed meter for interferometric displacement sensing. Two equivalent implementations are presented: an online approach that uses real-time…
