I'm fairly certain they

I'm fairly certain they already have one. This is probably just misdirection to make everyone thing that RSA still works. The reality is that they have all kinds of backdoors that circumvent the security. For example, hardware hacks installed during the interception of equipment in transit from the seller to the buyer is very hard to circumvent. nevertheless, they very likely do already have several types of quantum computers. After all, we have known since Shor's paper that it is possible to factor large primes in bounded polynomial time on a quantum computer since the late nineties.

To the comment below: DWave does claim to have an adiabatic quantum computer, but as I understand it, it cannot use Shor's algorithm to factor numbers.
