From: Application of Quantum Annealing to Nurse Scheduling Problem

The probability of finding a ground state of the Hamiltonian by using D-Wave 2000Q (left) and simulate annealing (right) for (blue) \(N=3\) and (red) \(N=4\) with respect to the number of days D in the schedule. Each error bar is generated by the standard deviation (1000 samples for 10 shots for D-Wave 2000Q and 500 annealing times 10 shots for SA).
