A robust and efficient solver for coupled cluster equations
Chanaka D. M. Mudiyanselage, Kangbo Li, Fabian M. Faulstich
The coupled-cluster (CC) equations are most frequently solved via fixed-point (FP) iterations. However, when formulated in a non-canonical gauge, as in local correlation CC, the FP…
Augmented Lagrangian method for coupled-cluster
Fabian M. Faulstich, Yuehaw Khoo, Kangbo Li
We propose to improve the convergence properties of the single-reference coupled cluster (CC) method through an augmented Lagrangian formalism. The conventional CC method changes a…
An unambiguous and robust formulation for Wannier localization
Kangbo Li, Hsin-Yu Ko, Robert A. DiStasio +1
We provide a new variational definition for the spread of an orbital under periodic boundary conditions (PBCs) that is continuous with respect to the gauge, consistent in the therm…
Scalable Hardware-Efficient Qubit Control with Single Flux Quantum Pulse Sequences
Kangbo Li, R. McDermott, Maxim G. Vavilov
The hardware overhead associated with microwave control is a major obstacle to scale-up of superconducting quantum computing. An alternative approach involves irradiation of the qu…
