New Hybrid Quantum Monte Carlo Algorithm
Researchers Xiaosi Xu and Ying Li have developed a “quantum-assisted” Monte Carlo method that uses a small quantum processor to boost the accuracy of classical simulations. The breakthrough, published in Quantum in 2023, addresses the notorious sign problem in quantum Monte Carlo calculations – a key issue that causes explosive uncertainty in simulations of electrons and other fermions. By incorporating…
