Diagonal Catalysts in Quantum Adiabatic Optimization
Tameem Albash, Matthew Kowalsky
We propose a protocol for quantum adiabatic optimization, whereby an intermediary Hamiltonian that is diagonal in the computational basis is turned on and off during the interpolat…
Comparing relaxation mechanisms in quantum and classical transverse-field annealing
Tameem Albash, Jeffrey Marshall
Annealing schedule control provides new opportunities to better understand the manner and mechanisms by which putative quantum annealers operate. By appropriately modifying the ann…
De-Signing Hamiltonians for Quantum Adiabatic Optimization
Elizabeth Crosson, Tameem Albash, Itay Hen +1
Quantum fluctuations driven by non-stoquastic Hamiltonians have been conjectured to be an important and perhaps essential missing ingredient for achieving a quantum advantage with…
Testing a quantum annealer as a quantum thermal sampler
Zoe Gonzalez Izquierdo, Tameem Albash, Itay Hen
Motivated by recent experiments in which specific thermal properties of complex many-body systems were successfully reproduced on a commercially available quantum annealer, we exam…
