Thermal State Preparation via Rounding Promises
Patrick Rall, Chunhao Wang, Pawel Wocjan
A promising avenue for the preparation of Gibbs states on a quantum computer is to simulate the physical thermalization process. The Davies generator describes the dynamics of an o…
Space-efficient Quantization Method for Reversible Markov Chains
Chen-Fu Chiang, Anirban Chowdhury, Pawel Wocjan
In a seminal paper, Szegedy showed how to construct a quantum walk for any reversible Markov chain such that its eigenvector with eigenphase is a quantum sample of t…
Quantum-enhanced Markov chain Monte Carlo
David Layden, Guglielmo Mazzola, Ryan V. Mishmash +4
Sampling from complicated probability distributions is a hard computational problem arising in many fields, including statistical physics, optimization, and machine learning. Quant…
