D-Wave 2000Q Now 150X Faster For Some Types Of Problems

[Lucian Armasu]

D-Wave announced two new features for its 2000Q quantum annealing computer: reverse annealing, bringing up to 150x speedup for certain problems, and virtual graphs, which improves the performance of certain machine learning algorithms by 5x.

How do you measure quantum performance? In the case of super computers, it's typically FLOPS. Does that still apply with a quantum processor?

Number of qubits seems the first-order metric. Other than that, it's a matter of relative speed at solving certain problems - sort of like benchmarks.

As the field matures, perhaps there'll be something like SpecQA, for Quantum Annealing. Maybe another SpecMark for general quantum computers.

I'd also watch for metrics related to setup/readout time, power & temperature requirements (or just operating costs), and stability/error rate.

I like the mention of using redundancy, in the form of multiple qubits. I was wondering if that could be an approach for reducing the error rate.
