Deterministic and programmable generation of mechanical multipartite entangled states
Isabelle Franzen, Max-Emanuel Kern, Q. Rumman Rahman +5
Multimode mechanical resonators offer a large set of densely packed, long-lived bosonic modes within a single compact device, making them attractive for quantum simulation, quantum…
Mixed-state phases induced by power-law quantum channels
Christopher Fechisin, Tsung-Cheng Lu, Zhi-Yuan Wei +4
Open quantum systems can exhibit inherently mixed quantum orders, such as strong-to-weak spontaneous symmetry breaking (SW-SSB), which have no analogue in pure states. It is genera…
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…
Renormalization-group-based preparation of matrix product states on up to 80 qubits
Moritz Scheer, Alberto Baiardi, Elisa Bäumer Marty +2
A key challenge for quantum computers is the efficient preparation of many-body entangled states across many qubits. In this work, we demonstrate the preparation of matrix product…
Measurement-induced entanglement in noisy 2D random circuits

We study measurement-induced entanglement (MIE) generated by column-by-column sampling of noisy 2D random circuits of size and depth . Focusing primarily on Clifford circuit…
State preparation with parallel-sequential circuits
Zhi-Yuan Wei, Daniel Malz
We introduce parallel-sequential (PS) circuits, a family of quantum circuit layouts that interpolate between brickwall and sequential circuits, which introduces control parameters…
Kondo impurity in an attractive Fermi-Hubbard bath: Equilibrium and dynamics
Zhi-Yuan Wei, Tao Shi, J. Ignacio Cirac +1
We investigate theoretically equilibrium and dynamical properties of a Kondo impurity coupled to either 1D or 2D superconductors, modeled by the attractive Fermi-Hubbard model. By…
