>>44 IBM does, you can find it by googling 'Experience IBM Quantum'
It's a superposition pun lol
It doesn't look like trit based crypto could really be any weaker than bit-based systems unless you're relying on some maximal scattering property, or they manage to build cutrits or cubitrits / cupentrits /etc
3^5 is also pretty close to 2^8 so that's kind of handy, only twelve values short

>>43,45 Is it an actual quantum computer as defined by, say, Feynman or is it a ``quantum computer'' as defined by IBM? To make the latter is trivial, you only need enough money for smoke and mirrors so the public believes it. The great thing about the five qubit computer is that classical computers can still easily imitate them, so you can even have a ``demo''.

>>47 It's probably somewhere in the middle, seriously
The design of the thing seems fairly weak also, a [q0 -> q1 -> q2 <- q3 <- q4] + [q0 -> q2 <- q4] layout doesn't really allow any classical cycles
