Faster Quantum Monte Carlo Simulation by Random Compilation
John M. Martyn, Joshua Lin, Neill C. Warrington +2
Quantum Monte Carlo (QMC) algorithms are among the most powerful classical methods for simulating quantum systems, yet their accuracy is often limited by the systematic errors in t…
Trading Imaginary Time for Randomness in Ground State Preparation
Alvan Arulandu, John M. Martyn, Isaac L. Chuang
Imaginary-time evolution (ITE) is a foundational method for ground state preparation on quantum computers. However, because ITE is non-unitary, existing implementations incur a sam…
Polynomial-time exact diagonalization via sparse guided eigenwalks
