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…
Implementation of Measurement Reduction for the Variational Quantum Eigensolver
Alexis Ralli, Peter Love, Andrew Tranter +1
One limitation of the variational quantum eigensolver algorithm is the large number of measurement steps required to estimate different terms in the Hamiltonian of interest. Unitar…
Contextual Subspace Variational Quantum Eigensolver
William M. Kirby, Andrew Tranter, Peter J. Love
We describe the contextual subspace variational quantum eigensolver (CS-VQE), a hybrid quantum-classical algorithm for approximating the ground state energy of a Hamiltonian. The a…
Ordering of Trotterization: Impact on Errors in Quantum Simulation of Electronic Structure
Andrew Tranter, Peter J. Love, Florian Mintert +2
Trotter-Suzuki decompositions are frequently used in the quantum simulation of quantum chemistry. They transform the evolution operator into a form implementable on a quantum devic…
Measurement reduction in variational quantum algorithms
Andrew Zhao, Andrew Tranter, William M. Kirby +3
Variational quantum algorithms are promising applications of noisy intermediate-scale quantum (NISQ) computers. These algorithms consist of a number of separate prepare-and-measure…
