Hybrid VQE-CVQE algorithm using diabatic state preparation
John P. T. Stenger, C. Stephen Hellberg, Daniel Gunlycke
We propose a hybrid variational quantum algorithm that has variational parameters used by both the quantum circuit and the subsequent classical optimization. Similar to the Variati…

Ground-state energies of Ising models calculated using the samples from a quantum computer that simulates short-time evolution
John P. T. Stenger, C. Stephen Hellberg, Daniel Gunlycke
We find the ground-state energy of the Ising model using the Cascaded Variational Quantum Eigensolver (CVQE) algorithm with the Guided-Sampling Ansatz (GSA) using up to 63 qubits o…

Guided sampling ansätzes for variational quantum computing
Daniel Gunlycke, John P. T. Stenger, Andrii Maksymov +3
Quantum computing is a promising technology because of the ability of quantum computers to process vector spaces with dimensions that increase exponentially with the simulated syst…
