Quantum Twist on Common Computer Algorithm Promises Speed Boost
Mazzola stresses the team is not yet claiming quantum advantage; the result demonstrates future potential, rather than current ability.

Scientists at Switzerland's University of Zurich (UZH) and IBM have demonstrated that a quantum version of the popular Monte Carlo algorithm could eventually overtake versions running on classical computers.
However, the researchers explained, attaining this speed advantage would probably require a quantum system with at least 1,000 quantum bits.
Said UZH's Guglielmo Mazzola, "If this works, it's going to enhance, by a lot, the way in which we model systems and that, in turn, will allow us to make better predictions in a wide range of fields."
However, he acknowledged that "we cannot exclude that our classical friends can devise something even better."
