Finite temperature quantum annealing solving exponentially small gap problem with non-monotonic success probability
The alternating sector chain Ising problem features an exponentially small energy gap in the sector size, so one would expect an exponential decrease in success probability on a quantum annealing device. Here, instead, the authors show a nonmonotonic behavior, explaining it in terms of thermally acc...

| Summary: | The alternating sector chain Ising problem features an exponentially small energy gap in the sector size, so one would expect an exponential decrease in success probability on a quantum annealing device. Here, instead, the authors show a nonmonotonic behavior, explaining it in terms of thermally accessible states. |
