We show how to modify the noiseless gate executed by the computer to include any Markovian noise, hence resulting in what we will call a noisy gate. We test our method against the IBM Qiskit simulator and show that it follows more closely both the analytical evolution of the Lindblad equation as well as the behavior of a real quantum computer, thus offering a more accurate noise simulator of NISQ devices. The method is flexible enough to potentially describe any noise, including non-Markovian ones.</p><p><strong>About the speakers</strong></p><p><span style=\"color:hsl(210,75%,60%);\"><strong>Giovanni di Bartolomeo</strong></span> and <span style=\"color:hsl(210,75%,60%);\"><strong>Michele Vischi</strong></span> are PhD students in the QMTS group at the University of Trieste.
