$O(N^3)$ 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 …

NAPA: Intermediate-level Variational Native-pulse Ansatz for Variational Quantum Algorithms

2022 · arXiv (Cornell University)

Variational quantum algorithms (VQAs) have demonstrated great potentials in the Noisy Intermediate Scale Quantum (NISQ) era. In the workflow of VQA, the parameters of ansatz are iteratively updated to approximate the desired quantum states. We …
