Re: Forgive my ignorance

Exactly. These machines are "available to the public", for some definition of "public", and have "practical" applications if your practice happens to be "let's see what we can do with toy problems using GQC, so we have a better idea of what we might be able to do with a large GQC". (Though, to be fair, even at 50 qubits you ought to be able to formulate problems that are intractable on classical computers; 250 is a respectably large number.)

But you're not going to use these machines to speed up your database searches with Grover's algorithm, or to crack 2048-bit RSA keys.
