Actually a couple of products, I will comment only on one of them, the quantum random number generator. It reminds me of using a sport-utility vehicle to drive to the neighbor's house, ten feet away. There are easier ways to get to there. There is no reason to believe that quantum noise has any practical advantage over thermal noise. This point is not discussed in Quantique's principles-of-operation paper http://www.idquantique.com/files/paper-qrng.pdf and indeed they say there "goal is to avoid" thermal noise. You can harvest industrial-strength randomness from the thermodynamics of electrical circuits, costing next to nothing.
