Direct Fidelity Estimation of Quantum States using Machine Learning
Xiaoqian Zhang, Maolin Luo, Zhaodi Wen +4
In almost all quantum applications, one of the key steps is to verify that the fidelity of the prepared quantum state meets expectations. In this Letter, we propose a new approach…
Optimal measurements for quantum multiparameter estimation with general states
Jing Yang, Shengshi Pang, Yiyu Zhou +1
We generalize the approach by Braunstein and Caves [Phys. Rev. Lett. 72, 3439 (1994)] to quantum multi-parameter estimation with general states. We derive a matrix bound of the cla…
Quantum state tomography with time-continuous measurements: reconstruction with resource limitations
Areeya Chantasri, Shengshi Pang, Teerawat Chalermpusitarak +1
We propose and analyze quantum state estimation (tomography) using continuous quantum measurements with resource limitations, allowing the global state of many qubits to be constru…
Abrupt transitions between Markovian and non-Markovian dynamics in open quantum systems
Shengshi Pang, Todd A. Brun, Andrew N. Jordan
A rapid restoration of the bath state is usually required to induce Markovian dynamics for an open quantum system, which typically can be realized only in limits such as weak syste…
Precision optical displacement measurements using biphotons
Kevin Lyons, Shengshi Pang, Paul G. Kwiat +1
We propose and examine the use of biphoton pairs, such as those created in parametric down conversion or four-wave mixing, to enhance the precision and the resolution of measuring…
