Scaling of Hybrid Quantum Classical Annealing — •Aditi Misra-Spieldenner1, Peter Ken Schuhmacher1, Xi Dai2, Salil Bedkihal2, and Frank K Wilhelm1 — 1Universität des Saarlandes — 2University of Waterloo
In an earlier work an efficient gap-independent cooling scheme has been proposed for a quantum annealer that benefits from finite temperatures for single qubit systems based on superconducting flux qubit [1]. In our current work we extend this investigation to systems containing larger number of qubits. We simulate random annealing schedules using a well established path integral method called 'Quasi Adiabatic Propagator Path Integral' (QUAPI). We investigate different cooling methods to counter noise and heating that arise from always present longitudinal thermal noise.
