Teleportation-based filtering for gravitational-wave detectors
Yohei Nishino
Employing the principle of quantum teleportation in gravitational-wave detectors provides a method to address technical challenges associated with implementing quantum filters for…
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…
Frequency-dependent squeezing for gravitational-wave detection through quantum teleportation
Yohei Nishino, Stefan Danilishin, Yutaro Enomoto +1
Ground-based interferometric gravitational wave detectors are highly precise sensors for weak forces, limited in sensitivity across their detection band by quantum fluctuations of…
Variational readout through quantum teleportation
Yohei Nishino
Sensitivity of gravitational-wave detectors (GWDs) is constrained at low frequencies by quantum radiation-pressure noise, a manifestation of the measurement's back action. One stra…
