Current quantum computers contain hundreds of qubits a number large enough to perform interesting tasks. However, quantum computers are far from being ideal: they are prone to errors due to noises, which limit their capabilities. The scientific community is devoting a lot of effort in order to understand the impact of noises, because this is of crucial importance in order to reach the ultimate goal of fault-tolerant quantum computation. Our work fits into this context, we present a novel method for incorporating more efficiently environmental effects in the execution of any algorithm on real quantum computers providing a step forward a more realistic and precise analysis of the noises’ behavior with respect to other existing approaches.
