* Ideally, the probability of observing a heavy output would be estimated using all of the qubits of a large device, but NISQ devices have appreciable error rates, so we begin with small model circuits and progress to larger ones. | * Ideally, the probability of observing a heavy output would be estimated using all of the qubits of a large device, but NISQ devices have appreciable error rates, so we begin with small model circuits and progress to larger ones. | ||
