Leakage Suppression in Quantum Control via Static Parameter Offsets
Ting Lin, Zi-Hao Qin, Zheng-Yuan Xue +1
High-fidelity quantum operations require the system dynamics to be strictly confined to the computational subspace. In practice, however, control fields inevitably couple to leakag…
Universal Robust Quantum Gates via Doubly Geometric Control
Hai Xu, Tao Chen, Junkai Zeng +5
Geometric quantum computation offers a potential route to fault-tolerant quantum information processing by exploiting the global nature of geometric phases. However, achieving cont…
Determining a magnetic Schrödinger equation by a single far-field measurement
Chaohua Duan, Zhen Xue
This paper investigates the inverse scattering problem for the magnetic Schrödinger equation. We first establish the well-posedness of the direct problem through a variational appr…
Variational Quantum Algorithm for Solving the Liouvillian Gap
Xu-Dan Xie, Zheng-Yuan Xue, Dan-Bo Zhang
In open quantum systems, the Liouvillian gap characterizes the relaxation time toward the steady state. However, accurately computing this quantity is notoriously difficult due to…
Robustness Enhancement of Universal Noncyclic Geometric Gates via Evolution Optimization
Zi-Hao Qin, Yan Liang, Yi-Han Yuan +2
Noncyclic geometric gates aim to overcome the stringent constraints of conventional cyclic conditions and enhance the flexibility in evolution choice. Conceptually, they can also a…
Error-mitigated Geometric Quantum Control over an Oscillator
Ming-Jie Liang, Tao Chen, Zheng-Yuan Xue
Quantum information is very fragile to environmentally and operationally induced imperfections. Therefore, the construction of practical quantum computers requires quantum error-co…
