内容記述 |
Estimating the energy of a Hamiltonian is one of the most important tasks and frequently addressed in a quantum-classical hybrid algorithm like VQE (Variational Quantum Eigensolver). Grouping of Pauli operators plays a key role to improve efficiency of the energy estimation taking advantage of simultaneous measurements. However, the grouping of large molecules is difficult in terms of both computation time and memory space required. We propose a parallelized algorithm of grouping to address this issue. We succeeded to compute grouping of a large set of Pauli operators, which could not be computed before. |
