$O(N^3)$ Measurement Cost for Variational Quantum Eigensolver on Molecular Hamiltonians

2020 · IEEE Transactions on Quantum Engineering

Variational quantum eigensolver (VQE) is a promising algorithm for near-term quantum machines. It can be used to estimate the ground state energy of a molecule by performing separate measurements of O(N4) terms. This quartic scaling …

Adapting Quantum Approximation Optimization Algorithm (QAOA) for Unit Commitment

2021

In the present Noisy Intermediate-Scale Quantum (NISQ), hybrid algorithms that leverage classical resources to reduce quantum costs are particularly appealing. We formulate and apply such a hybrid quantum-classical algorithm to a power system optimization problem …

CAFQA: A Classical Simulation Bootstrap for Variational Quantum Algorithms

2022

Classical computing plays a critical role in the advancement of quantum frontiers in the NISQ era. In this spirit, this work uses classical simulation to bootstrap Variational Quantum Algorithms (VQAs). VQAs rely upon the iterative …
