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…
TensorCircuit-NG: A Universal, Composable, and Scalable Platform for Quantum Computing and Quantum Simulation
