Quantum energy gaps and first-order mean-field transitions
... In a nutshell, the reason why quantum annealing is not an efficient strategy for finding the ground state across a first-order transition can be understood from a simple, qualitative argument. Quantum annealing could in principle be more efficient than thermal annealing for certain classes of proble ...

... In this experiment, switching between the two channels occurs about each 10 ns. Since this delay, as well as the lifetime of the intermediate level of the cascade (5 ns), is small compared to L/c (40 ns), a detection event on one side and the corresponding change of orientation on the other side are ...

Optimal parallel quantum query algorithms
... free. For every function, we have Q(f )/p ≤ Qpk (f ) ≤ Q(f ). An extreme case of the parallel model is where p large enough so that Qpk (f ) becomes 1; such algorithms are called “nonadaptive,” because all queries are made in parallel. Montanaro [28] showed that for total functions, such nonadaptive ...
