Increased success probability in Hardy's nonlocality: Theory and demonstration
Duc Minh Tran, Van-Duy Nguyen, Le Bin Ho +1
Depending on the way one measures, quantum nonlocality might manifest more visibly. Using basis transformations and interactions on a particle pair, Hardy logically argued that any…
Stochastic approach for quantum metrology with generic Hamiltonians
Le Bin Ho
Recently, variational quantum metrology was proposed for Hamiltonians with multiplicative parameters, wherein the estimation precision can be optimized via variational circuits. Ho…
Quantum backaction effects in sequential measurements
Le Bin Ho
Quantum backaction refers to the disturbance of a quantum system caused by measuring it. In sequential measurements, this effect can accumulate and become significant, leading to n…
High Q mg-scale monolithic pendulum for quantum-limited gravity measurements
Seth B. Cataño-Lopez, Jordy G. Santiago-Condori, Keiichi Edamatsu +1
We present the development of a high monolithic silica pendulum weighing 7 mg. The measured value for the pendulum mode at 2.2 Hz was . To the best of our kn…
Atto-Nm Torque Sensing with a Macroscopic Optomechanical Torsion Pendulum
Kentaro Komori, Yutaro Enomoto, Ching Pin Ooi +5
Precise measurements of the displacement of, and force acting on, a mechanical oscillator can be performed by coupling the oscillator to an optical cavity. Brownian thermal forces…
Demonstration of displacement sensing of a mg-scale pendulum for mm- and mg- scale gravity measurements
Nobuyuki Matsumoto, Masakazu Sugawara, Seiya Suzuki +6
Gravity generated by large masses has been observed using a variety of probes from atomic interferometers to torsional balances. However, gravitational coupling between small masse…
Direct measurement of the optical trap-induced decoherence
Nobuyuki Matsumoto, Kentaro Komori, Sosuke Ito +2
Thermal decoherence is a major obstacle to the realization of quantum coherence for massive mechanical oscillators. Although optical trapping has been used to reduce the thermal de…
