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 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…
Augmenting Finite Temperature Tensor Network with Clifford Circuits
Xiangjian Qian, Jiale Huang, Mingpu Qin
Recent studies have highlighted the combination of tensor network methods and the stabilizer formalism as a very effective framework for simulating quantum many-body systems, encom…
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…
From Tree Tensor Network to Multiscale Entanglement Renormalization Ansatz
Xiangjian Qian, Mingpu Qin
Tensor Network States (TNS) offer an efficient representation for the ground state of quantum many body systems and play an important role in the simulations of them. Numerous TNS…
