There was actually a more powerful (yet more expensive) Quantum computer by Google. 72-qbit, although for purposes of comparison let's not count with it, because there are a couple of differences here (some hard to explain). Intel also had a 49-qbit even before the 72-qbit one from Google.

IBM also has a 53-qbit Quantum Computer.

But what I find interesting in this new Google quantum processor is the attempt to reduce the way of cooling these computers, in this case using "Nonlinear superconducting resonator", which is similar to saying, "we are trying to make cooling cheaper".

Maybe my next supercomputer will be a Quantum computer... LOL who knows... (I am actually not joking here, because I work on HPC, High Performance Computing).
