Enhancement of Quantum Sensing in a Cavity Optomechanical System around Quantum Critical Point
Shao-Bo Tang, Hao Qin, D. -Y. Wang +4
The precision of quantum sensing could be improved by exploiting quantum phase transitions, where the physical quantity tends to diverge when the system approaches the quantum crit…

Peng Xue, Rong Zhang, Zhihao Bian +3
We realize a pair of simultaneous ten-step one-dimensional quantum walks with two walkers sharing coins, which we prove is analogous to the ten-step two-dimensional quantum walk wi…

Zhihao Bian, Jian Li, Hao Qin +4
We perform generalized measurements of a qubit by realizing the qubit as a coin in a photonic quantum walk and subjecting the walker to projective measurements. Our experimental te…

Peng Xue, Rong Zhang, Hao Qin +3
We introduce and analyze a one-dimensional quantum walk with two time-independent rotations on the coin. We study the influence on the property of quantum walk due to the second ro…
Trapping photons on the line: controllable dynamics of a quantum walk
P. Xue, H. Qin, B. Tang
We demonstrate a coined quantum walk over ten steps in a one-dimensional network of linear optical elements. By applying single-point phase defects, the translational symmetry of a…
Observation of quasiperiodic dynamics in a one-dimensional quantum walk of single photons in space
Peng Xue, Hao Qin, Bao Tang +1
We realize quasi-periodic dynamics of a quantum walker over 2.5 quasi-periods by realizing the walker as a single photon passing through a quantum-walk optical-interferometer netwo…
