Scalable cavity QED quantum computer? Not yet…

This Story:

Demonstration of two-qubit algorithms with a superconducting quantum processor

Is being reported in several places at the moment, see here and here for example.

Whilst I’m confident that it works well in the few qubit limit, I’m not at all convinced that cavity QED is a scalable QC architecture. We’ve done some work on this architecture ourselves. There’s only so many qubits you can fit into one of these microwave resonators, and that’s without thinking about bias lines, error correction etc… I’d like to see a proposal for a scalable version.

  1. […] for ages – what’s all this ‘first’ business? Besides, didn’t Yale do something similar a few months back? Oh no, wait a minute, they actually ran an algorithm… And that’s without even […]
