Subspace Diagonalization on Quantum Computers using Eigenvector Continuation
Akhil Francis, Anjali A. Agrawal, Jack H. Howard +2
Quantum subspace diagonalization (QSD) methods are quantum-classical hybrid methods, commonly used to find ground and excited state energies by projecting the Hamiltonian to a smal…
Many Body Thermodynamics on Quantum Computers via Partition Function Zeros
Akhil Francis, D. Zhu, C. Huerta Alderete +6
Interacting quantum systems illustrate complex phenomena including phase transitions to novel ordered phases. The universal nature of critical phenomena reduces their description t…
Quantum computation of magnon spectra
Akhil Francis, J. K. Freericks, A. F. Kemper
We demonstrate quantum computation of two-point correlation functions for a Heisenberg spin chain. Using the IBM Q 20 quantum machines, we find that for two sites the correlation f…
