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…
Sequential quantum nonlocality sharing under local noisy quantum channels
Na Li, Chen-Yue Li, Yu-Hong Zheng +3
Sequential sharing of quantum nonlocality (SSQN) is crucial for device-independent tasks in quantum information processing, wherein relaying the post-measurement qubit through a lo…
Pontryagin's Principle for Leakage-Immune Adiabatic Quantum State Transfer
Xiao-Yu Dong, Xi-Lai Wang, Wen-Long Ma
The standard stimulated Raman adiabatic passage (STIRAP) protocol enables high-fidelity quantum state transfer in an ideal three-level system via adiabatic following of a dark stat…
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,…
Quantum-Classical Boundary Engineering in Weak-to-Strong Measurements via Squeezed Vacua
Janarbek Yuanbek, Wen-Long Ma, Yusuf Turek
This study establishes a post-selected von Neumann framework to regulate non-classical features of single-photon-subtracted squeezed vacuum (SPSSV) and two-mode squeezed vacuum (TM…
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…
Diverse methods and practical aspects in controlling single semiconductor qubits: a review
Jia-Ao Peng, Chu-Dan Qiu, Wen-Long Ma +1
Quantum control allows a wide range of quantum operations employed in molecular physics, nuclear magnetic resonance and quantum information processing. Thanks to the existing micro…
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…
Diagnosing Quantum Phases Using Long-Range Two-Site Quantum Resource Behaviors
Lin-Lin Su, Jun Ren, Wen-Long Ma +2
We propose and demonstrate that the behaviors of long-range, two-site quantum resources can effectively diagnose quantum phases. In an XX spin chain with symmetry-breaking quantum…
