A Scalable Distributed Quantum Optimization Framework via Factor Graph Paradigm
Yuwen Huang, Xiaojun Lin, Bin Luo +1
Distributed quantum computing (DQC) connects many small quantum processors into a single logical machine, offering a practical route to scalable quantum computation. However, most…
Quantum Algorithms for Finite-horizon Markov Decision Processes
Bin Luo, Yuwen Huang, Jonathan Allcock +3
In this work, we design quantum algorithms that are more efficient than classical algorithms to solve time-dependent and finite-horizon Markov Decision Processes (MDPs) in two dist…
Graph-Cover-based Characterization of the Bethe Partition Function of Double-Edge Factor Graphs
Yuwen Huang, Pascal O. Vontobel
For standard factor graphs (S-FGs) with non-negative real-valued local functions, Vontobel provided a combinatorial characterization of the Bethe approximation of the partition fun…
Sets of Marginals and Pearson-Correlation-based CHSH Inequalities for a Two-Qubit System
Yuwen Huang, Pascal O. Vontobel
Quantum mass functions (QMFs), which are tightly related to decoherence functionals, were introduced by Loeliger and Vontobel [IEEE Trans. Inf. Theory, 2017, 2020] as a generalizat…
