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…
Direct characterization of classical dephasing noise for a qubit
Yuan-De Jin, Zheng-Fei Ye, Wen-Long Ma
We propose a general method to characterize classical stochastic noise causing qubit dephasing through repetitive Ramsey interferometry measurements (RIMs) on the qubit. Compared t…
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…
How coherence measurements of a qubit steer its quantum environment
Chu-Dan Qiu, Yuan-De Jin, Jun-Xiang Zhang +2
Repetitive Ramsey interferometry measurements (RIMs) are often used to measure qubit coherence, assuming that the environment remains unaffected after each measurement and the outc…
Theory of Metastability in Discrete-Time Open Quantum Dynamics
Yuan-De Jin, Chu-Dan Qiu, Wen-Long Ma
Metastability in open system dynamics describes the phenomena of initial relaxation to longlived metastable states before decaying to the asymptotic stable states. It has been pred…
Channel-based framework for phase esimation of multiple eigenvalues
Yuan-De Jin, Shi-Yu Zhang, Wen-Long Ma
Quantum phase estimation (QPE) of the eigenvalues of a unitary operator on a target quantum system is a crucial subroutine in various quantum algorithms. Conventional QPE is often…
