| Summary:

Interesting problems in quantum computation take the form of finding
low-energy states of (pseudo)spin systems with engineered Hamiltonians that
encode the problem data. Motivated by the practical possibility of producing
very low-temperature spin systems, we propose and exemplify the possibility to
compute by coupling the computational spins to a non-Markovian bath of spins
that serve as a heat sink. We demonstrate both analytically and numerically
that this strategy can achieve quantum advantage in the Grover search problem.
