Error-Tolerant Geometric Quantum Control for Logical Qubits with Minimal Resource
Tao Chen, Zheng-Yuan Xue, Z. D. Wang
Geometric quantum computation offers a practical strategy toward robust quantum computation due to its inherently error tolerance. However, the rigorous geometric conditions lead t…
Quantum Gaussian filter for exploring ground-state properties
Min-Quan He, Dan-Bo Zhang, Z. D. Wang
Filter methods realize a projection from a superposed quantum state onto a target state, which can be efficient if two states have sufficient overlap. Here we propose a quantum Gau…
Path-optimized nonadiabatic geometric quantum computation on superconducting qubits
Cheng-Yun Ding, Li-Na Ji, Tao Chen +1
Quantum computation based on nonadiabatic geometric phases has attracted a broad range of interests, due to its fast manipulation and inherent noise resistance. However, it is limi…
Nonadiabatic geometric quantum computation with shortened path on superconducting circuits
Cheng-Yun Ding, Yan Liang, Kai-Zhi Yu +1
Recently, nonadiabatic geometric quantum computation has been received much attention, due to its fast manipulation and intrinsic error-resilience characteristics. However, to obta…
Fast high-fidelity geometric gates for singlet-triplet qubits
Mei-Ya Chen, Chengxian Zhang, Zheng-Yuan Xue
Geometric gates that use the global property of the geometric phase is believed to be a powerful tool to realize fault-tolerant quantum computation. However, for singlet-triplet qu…
Composite Short-path Nonadiabatic Holonomic Quantum Gates
Yan Liang, Pu Shen, Tao Chen +1
Nonadiabatic holonomic quantum computation (NHQC) has attracted significant attention due to its fast evolution and the geometric nature induced resilience to local noises. However…
