The Grassmann time-evolving matrix product operator method has shown great potential as a general-purpose quantum impurity solver, as its numerical errors can be well-controlled an…
Dynamical multipartite entanglement in a generalized Tavis-Cummings model with XY spin interaction
Yuguo Su, Zhijie Sun, Yiying Yan +5
Multipartite entanglement is a long-term pursuit in the resource theory, offering a potential resource for quantum metrology. Here, we present the dynamical multipartite entangleme…
Infinite Grassmann time-evolving matrix product operators for quantum impurity problems after a quench
Zhijie Sun, Ruofan Chen, Zhenyu Li +1
An emergent numerical approach to solve quantum impurity problems is to encode the impurity path integral as a matrix product state. For time-dependent problems, the cost of this a…
Circuit-Efficient Qubit-Excitation-based Variational Quantum Eigensolver
