Entanglement structure of the dynamical phases in the sub-Ohmic spin-boson model
Cunxi Gong, Zirui Sheng, Weitang Li
The sub-Ohmic spin-boson model exhibits three distinct dynamical regimes in its spin population dynamics, classified as coherent, incoherent, and pseudo-coherent. Whether these reg…
Automated Unitary Coupled Cluster Circuit Design via Differentiable Quantum Architecture Search
Jianpeng Chen, Zirui Sheng, Cunxi Gong +1
Designing compact and accurate circuits for the variational quantum eigensolver (VQE) is a central challenge in near-term quantum chemistry. Existing adaptive methods such as ADAPT…
Quantum-Classical Hybrid Computation of Electron Transfer in a Cryptochrome Protein via VQE-PDFT and Multiscale Modeling
Yibo Chen, Zirui Sheng, Weitang Li +4
Accurate calculation of strongly correlated electronic systems requires proper treatment of both static and dynamic correlations, which remains challenging for conventional methods…
Quantum Machine Learning of Molecular Energies with Hybrid Quantum-Neural Wavefunction
Weitang Li, Shi-Xin Zhang, Zirui Sheng +3
Quantum computational chemistry holds great promise for simulating molecular systems more efficiently than classical methods by leveraging quantum bits to represent molecular wavef…
