Unitary Partitioning and the Contextual Subspace Variational Quantum Eigensolver
Alexis Ralli, Tim Weaving, Andrew Tranter +3
The contextual subspace variational quantum eigensolver (CS-VQE) is a hybrid quantum-classical algorithm that approximates the ground-state energy of a given qubit Hamiltonian. It…
A stabilizer framework for Contextual Subspace VQE and the noncontextual projection ansatz
Tim Weaving, Alexis Ralli, William M. Kirby +3
Quantum chemistry is a promising application for noisy intermediate-scale quantum (NISQ) devices. However, quantum computers have thus far not succeeded in providing solutions to p…
A Scalable Approach to Quantum Simulation via Projection-based Embedding
Alexis Ralli, Michael I. Williams, Peter V. Coveney
Owing to the computational complexity of electronic structure algorithms running on classical digital computers, the range of molecular systems amenable to simulation remains tight…
