A polynomial-time classical sampler for noisy quantum circuits from statistical mechanics
Jon Nelson, Joel Rajakumar, Chao Yin +2
Developing classical simulation algorithms for noisy quantum circuits is essential to delineating the limits of quantum advantage. Existing classical sampling approaches for genera…

Noise-induced contraction of MPO truncation errors in noisy random circuits and Lindbladian dynamics
Zhi-Yuan Wei, Joel Rajakumar, Jon Nelson +3
We study how matrix-product-operator (MPO) truncation errors evolve when simulating two setups: (1) 1D Haar-random circuits under either depolarizing noise or amplitude-damping noi…
