QuSAnn v1.2 and Multiplexor Expander v1.2 are two Java applications available for free. (Source code included in the distribution.) QuSAnn is a ``code generator" for quantum simulated annealing: after the user inputs some parameters, it outputs a quantum circuit for performing simulated annealing on a quantum computer. The quantum circuit implements the algorithm of Wocjan et al.(arXiv:0804.4259), which improves on the original algorithm of Somma et al.(arXiv:0712.1008). The quantum circuit generated by QuSAnn includes some quantum multiplexors. The application Multiplexor Expander allows the user to replace each of those multiplexors by a sequence of more elementary gates such as multiply controlled NOTs and qubit rotations.
