Post-selected von Neumann measurement with Hermite-Gaussian and Laguerre-Gaussian pointer states
Yusuf Turek, Hirokazu Kobayashi, Tomotada Akutsu +2
Through the von Neumann interaction followed by post-selection, we can extract not only the eigenvalue of an observable of the measured system but also the weak value. In this post…
Multiple phase estimation in quantum cloning machines
Yao Yao, Li Ge, Xing Xiao +2
Since the initial discovery of the Wootters-Zurek no-cloning theorem, a wide variety of quantum cloning machines have been proposed aiming at imperfect but optimal cloning of quant…
Mechanical PT symmetry in coupled optomechanical systems
Xun-Wei Xu, Yu-xi Liu, Chang-Pu Sun +1
We propose to realize mechanical parity-time PT symmetry in two coupled optomechanical systems. To provide gain to one mechanical resonator and the same amount of damping to the ot…
Quantum fisher information in noninertial frames
Yao Yao, Xing Xiao, Li Ge +2
We investigate the performance of quantum fisher information under the Unruh-Hawking effect, where one of the observers (eg, Rob) is uniformly accelerated with respect to other par…
