Multiple phase estimation for arbitrary pure states under white noise
Yao Yao, Li Ge, Xing Xiao +2
In any realistic quantum metrology scenarios, the ultimate precision in the estimation of parameters is limited not only by the so-called Heisenberg scaling, but also the environme…
Distribution of quantum Fisher information in asymmetric cloning machines
Xing Xiao, Yao Yao, Lei-Ming Zhou +1
An unknown quantum state cannot be copied on demand and broadcast freely due to the famous no-cloning theorem. Approximate cloning schemes have been proposed to achieve the optimal…
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…
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…
