Characterization of entangling properties of quantum measurement via two-mode quantum detector tomography using coherent state probes
Shota Yokoyama, Nicola Dalla Pozza, Takahiro Serikawa +5
Entangled measurement is a crucial tool in quantum technology. We propose a new entanglement measure of multi-mode detection, which estimates the amount of entanglement that can be…
Spectrum analysis with quantum dynamical systems
Shilin Ng, Shan Zheng Ang, Trevor A. Wheatley +4
Measuring the power spectral density of a stochastic process, such as a stochastic force or magnetic field, is a fundamental task in many sensing applications. Quantum noise is bec…
Improved mirror position estimation using resonant quantum smoothing
Trevor A. Wheatley, Mankei Tsang, Ian R. Petersen +1
Quantum parameter estimation, the ability to precisely obtain a classical value in a quantum system, is very important to many key quantum technologies. Many of these technologies…
Utilizing weak pump depletion to stabilize squeezed vacuum states
Timo Denker, Dirk Schütte, Maximilian H. Wimmer +3
We propose and demonstrate a pump-phase locking technique that makes use of weak pump depletion (WPD) - an unavoidable effect that is usually neglected - in a sub-threshold optical…
Quantum-enhanced optical phase tracking
Hidehiro Yonezawa, Daisuke Nakane, Trevor A. Wheatley +10
Tracking a randomly varying optical phase is a key task in metrology, with applications in optical communication. The best precision for optical phase tracking has till now been li…
Adaptive Optical Phase Estimation Using Time-Symmetric Quantum Smoothing
T. A. Wheatley, D. W. Berry, H. Yonezawa +7
Quantum parameter estimation has many applications, from gravitational wave detection to quantum key distribution. We present the first experimental demonstration of the time-symme…
