Accelerated Quantum-Assisted Selected Configuration Interaction via Fast-Annealing-Based Determinant Selection
Hayun Park, Younghun Kwon, Hunpyo Lee
Full configuration interaction (FCI) provides exact electronic structure within a given atomic basis, but its computational cost grows exponentially with the number of spin orbital…
Graph-based block-diagonalization of full configuration interaction Hamiltonian: H chains study
Hayun Park, Hunpyo Lee
We developed a graph-based block-diagonalization (GBBD) method for the full configuration interaction Hamiltonian of molecular systems to efficiently calculate the exact eigenvalue…
Computational Supremacy of Quantum Eigensolver by Extension of Optimized Binary Configurations
Hayun Park, Hunpyo Lee
We developed a quantum eigensolver (QE) which is based on an extension of optimized binary configurations measured by quantum annealing (QA) on a D-Wave Quantum Annealer (D-Wave QA…
Determination of Optimal Chain Coupling made by Embedding in D-Wave Quantum Annealer
Hayun Park, Hunpyo Lee
The qubits in a D-wave quantum annealer (D-wave QA) are designed on a Pegasus graph that is different from structure of a combinatorial optimization problem. This situation require…
Hubbard model on Semiclassical approximation in combination with an optimizer based on GPU technology
Hayun Park, Hunpyo Lee
We developed a semiclassical approximation method in combination with an adaptive moment estimation optimizer (SCA + ADAM) approach based on the PyTorch plus CUDA library on a the…
