Nonlinear dynamics and mechanical frequency combs with a Meissner-levitated micromagnet
Yiqi Wang, Trisha Madhavan, Vanessa Wachter +6
Nonlinearities in multimode mechanical systems can give rise to rich dynamical phenomena with great potential for sensing applications and for future quantum experiments. We demons…
Probing the Error-Mitigation Threshold with Matrix Product States
Jia-Yao Zhao, Zhi-Yuan Wei, Michael J. Gullans
Quantum error mitigation relies on accurate noise characterization, but mismatches between the actual and characterized noise can be amplified and drive a sharp threshold between s…
Super-Logarithmic Entanglement Scaling in a Monitored Superconducting Chain
Rui-Jing Guo, Zhi-Yuan Wei
We study the entanglement dynamics of a one-dimensional spinful -wave superconductor subjected to local continuous measurements. In the rare-measurement regime, we derive a repl…
Fock-state preparation based on amplitude amplification in cavity QED
Sharoon Austin, Zhi-Yuan Wei, Kartik Srinivasan +1
In this work, we develop a coherent control technique for cavity QED based on amplitude amplification. We consider two physical platforms. In the first setting, we study a three-le…
Measurement-enhanced entanglement in a monitored superconducting chain
Rui-Jing Guo, Ji-Yao Chen, Zhi-Yuan Wei
A common view in monitored quantum dynamics is that local measurements suppress entanglement growth. We show that this intuition can fail in a one-dimensional spinful fermionic cha…
Weighted Nested Commutators for Scalable Counterdiabatic State Preparation
Jialiang Tang, Xi Chen, Zhi-Yuan Wei
Counterdiabatic (CD) driving enables efficient quantum state preparation, but it requires implementing highly nonlocal adiabatic gauge potentials (AGP) that are impractical to comp…
