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…
Nonadiabatic geometric quantum gates with on-demand trajectories
Yan Liang, Zheng-Yuan Xue
High-fidelity quantum gates are an essential prerequisite for large-scale quantum computation. When manipulating practical quantum systems, environmentally and operationally induce…
Scalable protocol to mitigate crosstalk in universal quantum gates
Yan Liang, Ming-Jie Liang, Sai Li +2
High-fidelity universal quantum gates are widely acknowledged as essential for scalable quantum computation. However, in solid-state quantum systems, which hold promise as physical…
Nonadiabatic Holonomic Quantum Computation and Its Optimal Control
Yan Liang, Pu Shen, Tao Chen +1
Geometric phase has the intrinsic property of being resistant to some types of local noises as it only depends on global properties of the evolution path. Meanwhile, the non-Abelia…
