Quantum Computing by Cooling
Jiajin Feng ; Biao Wu ; Frank Wilczek ;
Date 14 Jun 2021
AbstractInteresting problems in quantum computation take the form of finding low-energy states of 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.
