Fast two-dimensional tensor-network contraction via subspace iteration
Speeding up quantum simulations by doing math smarter, not harder
Physicists have developed a faster way to simulate quantum systems by replacing expensive mathematical operations with cheaper ones that run well on modern computers. The new method is up to 100 times faster than the previous standard approach, completing calculations on a single graphics processor that would have taken vastly longer before.
Quantum simulations help physicists understand materials and systems too complex to study experimentally, with applications ranging from discovering new superconductors to designing better batteries. Dramatically faster computation means researchers can tackle larger, more realistic quantum problems and get answers in hours instead of days or weeks, accelerating the pace of discovery in materials science and quantum physics.
