Correlated pair ansatz with a binary tree structure
Rishab Dutta, Fei Gao, Armin Khamoshi +2
We develop an efficient algorithm to implement the recently introduced binary tree state (BTS) ansatz on a classical computer. BTS allows a simple approximation to permanents arisi…
State preparation of AGP on a quantum computer without number projection
Armin Khamoshi, Rishab Dutta, Gustavo E. Scuseria
The antisymmetrized geminal power (AGP) is equivalent to the number projected Bardeen-Cooper-Schrieffer (PBCS) wavefunction. It is also an elementary symmetric polynomial (ESP) sta…
AGP-based unitary coupled cluster theory for quantum computers
Armin Khamoshi, Guo P. Chen, Francesco A. Evangelista +1
Electronic structure methods typically benefit from symmetry breaking and restoration, specially in the strong correlation regime. The same goes for Ansätze on a quantum computer.…
Exploring non-linear correlators on AGP
Armin Khamoshi, Guo P. Chen, Thomas M. Henderson +1
Single-reference methods such as Hartree-Fock-based coupled cluster theory are well known for their accuracy and efficiency for weakly correlated systems. For strongly correlated s…
Correlating AGP on a quantum computer
Armin Khamoshi, Francesco A. Evangelista, Gustavo E. Scuseria
For variational algorithms on the near term quantum computing hardware, it is highly desirable to use very accurate ansatze with low implementation cost. Recent studies have shown…
Efficient evaluation of AGP reduced density matrices
Armin Khamoshi, Thomas Henderson, Gustavo Scuseria
We propose and implement an algorithm to calculate the norm and reduced density matrices of the antisymmetrized geminal power (AGP) of any rank with polynomial cost. Our method sca…
Observation of Valley Zeeman and Quantum Hall Effects at Q Valley of Few-Layer Transition Metal Disulfides
Zefei Wu, Shuigang Xu, Huanhuan Lu +10
In few-layer (FL) transition metal dichalcogenides (TMDC), the conduction bands along the Gamma-K directions shift downward energetically in the presence of interlayer interactions…
