Quantum cryptography finally commercialized?

Start-up MagiQ Technologies, from Somerville, Massachusetts, has released
the first commercial implementation of quantum cryptography, the
much-heralded solution to the perfect encryption cipher. Theoretically,
encryption ciphers created using quantum physics are unbreakable.

While MagiQ Technologies' product, Navajo, isn't itself a quantum device it
uses one of the fundamental tenets of quantum theory: Heisenberg's
Uncertainty Principle, to create a Quantum Key Distribution (QKD) network.
Werner Heisenberg first published his theory in 1927, stating that the more
precisely the position of is known, the less precisely the momentum is
known. This succinct statement addresses the uncertain relationship between
the position and the momentum (mass times velocity) of a subatomic
particle, such as an electron, and has profound impact on the development
of future information systems.
