I took a quick look at the dwave paper. It's the usual story: they present the device as though it's doing a noiseless evolution, when we know there's very high decoherence. They argue that simulating the noiseless evolution from first principles is hard

Our field would move a lot faster if more quantum information scientists took this advice from Anton Zeilinger!
When Anton Zeilinger received the award, he said, “My advice would be: Do what you find interesting, and don’t care too much about possible applications.”

Quantum hype and disinformation are damaging the field and misdirecting resources. But how do we measure quantum hype? As a first step to answering this question, I propose to establish some natural units to capture a typical instance of quantum nonsense.

This is a strange claim, since CS is already a branch of Physics.
Within 10-20 years, nearly every branch of science will be, for all intents and purposes, a branch of computer science.
Computational physics, comp chemistry, comp biology, comp medicine... Even comp archeology. Realistic simulations, big data analysis, and ML everywhere

I think in the case of quantum computing the field is in the process of fracturing into a bullshit-focused corporate-driven component and an evidence-based academic component. These are increasingly disconnected as the corporate component severs ties with reality.
Quantum computing is also heading in this direction, if it's not there yet.

QIP has inherited from CS a fetish for complication. It is our job as reviewers and PC members to fight the fallacy that simple-->trivial and complicated-->deep.

arXiv is a cancer that promotes the dissemination of junk "science" in a format that is indistinguishable from real publications. And promotes the hectic "can't keep up" + "anything older than 6 months is irrelevant" CS culture.

It really is hard to see how degraded the environment at IBM Research has become. This is a place that had a hand in discovering the foundations of quantum computing and information. Where Landauer, Bennett, DiVincenzo, Smolin, Terhal all stood up to phonies.
@Travis_Sch
This paper has lost IBM a lot of respect in the community - you can’t spin this away. Had it been posted on arXiv first the limitations of your classical comparison would have been discussed/exposed prior to publication, so why not?
