Feedback-controlled adiabatic quantum computation
We propose a simple feedback-control scheme for adiabatic quantum computation
with superconducting flux qubits. The proposed method makes use of existing
on-chip hardware to monitor the ground-state curvature, which is then used to
control the computation speed to maximize the success probability. We show that
this scheme can provide a polynomial speed-up in performance and that it is
possible to choose a suitable set of feedback-control parameters for an
arbitrary problem Hamiltonian.
