aiqbench analysis
This theoretical paper shows that adding Markovian classical noise during cooling can speed up a quantum system's approach to its zero-temperature state, which runs against the intuition that noise resembles a hot reservoir. The result is a preprint with no experimental validation yet. For quantum readers, the practical question is whether this effect can be exploited for faster qubit initialization or reset, which depends on the assumptions and on hardware tests.
Driving the cooling process of a quantum system via classical noise
arXiv:2610.21608v1 Announce Type: new Abstract: It is known that under particular hypotheses anomalous thermalization processes can occur, such as the Mpemba effect, consisting in a faster cooling down when the system is prepared in a hotter initial condition, thus making convenient to warm up the system before the freezing process in order to make it freeze in a shorter time. It is shown here that the action of a Markovian classical noise during the freezing process can accelerate the approach to the zero-temperature thermal state. This prediction is counterintuitive, especially after observing that a classical noise can be considered equivalent to the action of an infinite-temperature reservoir, since both drive the system toward the same state. These facts lead to the statement that warming up the system during the contact with a low-temperature reservoir can accelerate the cooling process.
