Accelerating quantum Gibbs sampling without quantum walks
Jiaqi Leng, Jiaqing Jiang, Lin Lin
Szegedy's quantum walk quadratically accelerates reversible classical Markov chains, but extending this mechanism to efficiently implementable quantum Gibbs samplers has remained c…
Thermal expectation estimation via single-trajectory Gibbs sampling with non-destructive measurements
Hongrui Chen, Jiaqing Jiang, Bowen Li +1
Estimating thermal expectation values of quantum many-body systems is a central challenge in physics, chemistry, and materials science. Standard quantum Gibbs sampling protocols ad…
Gibbs state preparation for commuting Hamiltonian: Mapping to classical Gibbs sampling
Yeongwoo Hwang, Jiaqing Jiang
Gibbs state preparation, or Gibbs sampling, is a key computational technique extensively used in physics, statistics, and other scientific fields. Recent efforts for designing fast…
Quantum Metropolis Sampling via Weak Measurement
Jiaqing Jiang, Sandy Irani
Gibbs sampling is a crucial computational technique used in physics, statistics, and many other scientific fields. For classical Hamiltonians, the most commonly used Gibbs sampler…
Commuting Local Hamiltonian Problem on 2D beyond qubits
Sandy Irani, Jiaqing Jiang
We study the complexity of local Hamiltonians in which the terms pairwise commute. Commuting local Hamiltonians (CLHs) provide a way to study the role of non-commutativity in the c…
