TOPIC: Nonadiabatic Quantum Computation

Abstract
The implementation of adiabatic protocols is often unfeasible or impractical. This motivates the study of intrinsically nonadiabatic quantum annealing schemes. To this end, heuristics derived from the Kibble-Zurek mechanism proves useful. Exploiting it, in the first part of the talk I derive a universal optimal stopping time for adiabatic quantum annealing in the presence of noise-induced stochastic Hamiltonian fluctuations. In the second part, I introduce a new class of algorithms that use spatial and temporal inhomogeneous protocols to drive strongly disordered quantum spin systems and minimize the residual energy of the final state.
