Finding QuantumCircuit package?

Hi – I’m in the process of learning more about Quantum Computing, and since I’m more of a programmer than a mathematician, tinkering with a simulator seems like a great way to do it. I’ve read several papers about the QuantumCircuit package for Mathematica and it sounds ideal. However, I can’t find the actual package. Is it published somewhere? If so, I’d love to know how to access it. Thanks! – David
