Disentangling Kitaev Quantum Spin Liquid
Xiang Li, Xiangjian Qian, Mingpu Qin
In this work, we investigate the Kitaev honeycomb model employing the recently developed Clifford Circuits Augmented Matrix Product States (CAMPS) method. While the model in the ga…
On the correlation between entanglement and the negative sign problem
Ping Xu, Yang Shen, Yuan-Yao He +1
In this work, we study the correlation between entanglement and the negative sign problem in quantum Monte Carlo for the simulation of low-dimensional strongly correlated quantum m…
Clifford circuits Augmented Matrix Product States for fermion systems
Jiale Huang, Xiangjian Qian, Mingpu Qin
Clifford circuits Augmented Matrix Product States (CAMPS) was recently proposed to leverage the advantages of both Clifford circuits and Matrix Product States (MPS). Clifford circu…
Numerical study of bi-layer two-orbital model for LaNiO on a plaquette ladder
Yang Shen, Jiale Huang, Xiangjian Qian +2
The recently discovered high- superconductivity in LaNiO with provides another intriguing platform to explore the microscopic mechanism of…
Disentangling critical quantum spin chains with Clifford circuits
Chaohui Fan, Xiangjian Qian, Hua-Chen Zhang +3
Clifford circuits can be utilized to disentangle quantum states with polynomial cost, thanks to the Gottesman-Knill theorem. Based on this idea, the Clifford circuits augmented mat…
Non-stabilizerness Entanglement Entropy: a measure of hardness in the classical simulation of quantum many-body systems
Jiale Huang, Xiangjian Qian, Mingpu Qin
Classical and quantum states can be distinguished by entanglement entropy, which can be viewed as a measure of quantum resources. Entanglement entropy also plays a pivotal role in…
