It would be good to have nontrivial qubit assemblies at all in in *solid state*. I don't think anyone has QC working yet. It's not obvious it is at all usable, even for number factoring (entangling and keeping entangled a large qubit constellation, error correction, suitable QC algorithms, etc). Does at all elliptical curve crypto map well to QC?
There's actually been quantum error correction for as long as ten years already, so I suspect that somewhere deep underground in the greater DC-area there's a giant QC that's actually starting to do some interesting things. But I'd also bet any amount of $$$ it's more than a decade behind anything in the electronic domain. The knee in the curve is several years away. The mapping between elliptical curve crypto and quantum algorithms is a very interesting question that I have no idea of. No doubt, however, the affinities (or lack thereof) is already known. Look for telltale odd standards-bodies pushes towards certain approaches. -TD
