Dismagicker: Unitary Gate for Non-Stabilizerness Reduction
Jiale Huang, Rongyi Lv, Xiangjian Qian +1
We introduce the notion of dismagicker: non-Clifford unitary gate designed to reduce the non-stabilizerness (also called magic) of quantum many-body states. Although both entanglem…
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…
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…
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…
Plaquette-type valence bond solid state in the - square-lattice Heisenberg model
Jiale Huang, Xiangjian Qian, Mingpu Qin
We utilize Density Matrix Renormalization Group (DMRG) and Fully Augmented Matrix Product States (FAMPS) methods to investigate the Valence Bond Solid (VBS) phase in the -$J_2…
From the Shastry-Sutherland model to the - Heisenberg model
Xiangjian Qian, Rongyi Lv, Jong Yeon Lee +1
We propose a generalized Shastry-Sutherland model which bridges the Shastry-Sutherland model and the - Heisenberg model. By employing large scale Density Matrix Renormali…
