Quantum Zeno and Anti-Zeno Responses: Universal Spectral Criterion for Measurement-Induced Decay
Yu-Xiang Chen, Yuan-De Jin, Wen-Long Ma
We develop a general framework for characterizing the response of an evolving quantum system to repetitive quantum measurements. Modeling each evolution-measurement cycle as a quan…
Universal Characterization of Classical Qubit Noise
Yuan-De Jin, Zheng-Fei Ye, Wen-Long Ma
We propose a general method to fully characterize a classical stochastic noise process causing qubit dephasing through repetitive Ramsey interferometry measurements (RIMs) on the q…
Resource-Efficient Noise Spectroscopy for Generic Quantum Dephasing Environments
Yuan-De Jin, Zheng-Fei Ye, Wen-Long Ma
We present a resource-efficient method based on repetitive weak measurements to directly measure the noise spectrum of a generic quantum environment that causes qubit phase decoher…
Spectrum measurement of quantum channels and application to Hamiltonian parameter estimation
Yuan-De Jin, Wen-Long Ma
Quantum channels describe the most general dynamics of open quantum systems. A quantum channel, as a linear map on vectorized quantum states, can be represented by a single matrix,…
General Approach to Error Detection of Bosonic Codes via Phase Estimation
Yuan-De Jin, Shi-Yu Zhang, Ulrik L. Andersen +1
We present a general approach to error detection of bosonic quantum error-correction codes via an adaptive quantum phase estimation algorithm assisted by a single ancilla qubit. Th…
Observation of metastability in open quantum dynamics of a solid-state system
Jun-Xiang Zhang, Yuan-De Jin, Chu-Dan Qiu +2
Metastability is a ubiquitous phenomenon in non-equilibrium physics and classical stochastic dynamics.It arises when the system dynamics settles in long-lived states before eventua…
