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…
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…
