Noise-Symmetry Optimization of Quantum Error-Corrected Metrology
Shuyun Su, Shengshi Pang
Quantum error correction (QEC) codes have emerged as a powerful tool to protect quantum-enhanced metrology against noise. However, the ability to correct errors alone does not guar…
Hamiltonian Conditions for Dark Modes in Multimode Bosonic Systems
Zuxin Wu, Shengshi Pang
Dark modes arise when destructive interference prevents selected bosonic degrees of freedom from coupling to environmental channels. We formulate a Hamiltonian criterion for identi…
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…
