Quibbs v1.3, a Java application available for free. (Source code included in the distribution.) Quibbs is a ``code generator" for quantum Gibbs sampling: after the user inputs some files that specify a classical Bayesian network, Quibbs outputs a quantum circuit for performing Gibbs sampling of that Bayesian network on a quantum computer. Quibbs implements an algorithm that combines various apple pie techniques such as: an adaptive fixed-point version of Grover's algorithm, Szegedy operators, quantum phase estimation and quantum multiplexors.
Quibbs shares many Java classes with other Java applications available at this website (QuanSuite, QuSAnn, and Multiplexor Expander). For this reason, all these Java applications have a single, unified version number, the most recent being 1.3 (as of April 13, 2010)
