Transversal Gates in Nonadditive Quantum Codes
Chao Zhang, Zipeng Wu, Shilin Huang +1
Transversal gates play a crucial role in suppressing error propagation in fault-tolerant quantum computation, yet they are intrinsically constrained: any nontrivial code encoding a…
Characterizing Quantum Codes via the Coefficients in Knill-Laflamme Conditions
Mengxin Du, Chao Zhang, Yiu-Tung Poon +1
Quantum error correction (QEC) is essential for protecting quantum information against noise, yet understanding the structure of the Knill-Laflamme (KL) coefficients from…
Demonstration of a variational quantum eigensolver with a solid-state spin system under ambient conditions
Xuliang Du, Yang Shen, Zipeng Wu +2
Quantum simulators offer the potential to utilize the quantum nature of a physical system to study another physical system. In contrast to conventional simulation, which experience…
Quantifying subspace entanglement with geometric measures
Xuanran Zhu, Chao Zhang, Bei Zeng
Determining whether a subspace spanned by certain quantum states is entangled and its entanglement dimensionality remains a fundamental challenge in quantum information science. Th…
Tapping into Permutation Symmetry for Improved Detection of k-Symmetric Extensions
Youning Li, Chao Zhang, Shi-Yao Hou +3
Symmetric extensions are essential in quantum mechanics, providing a lens to investigate the correlations of entangled quantum systems and to address challenges like the quantum ma…
Variational learning algorithms for quantum query complexity
Zipeng Wu, Shi-Yao Hou, Chao Zhang +2
