With all due respect I think the title of the article “Ultra-efficient frequency conversion in quasi-phase-matched lithium niobate microrings” is better than the editorialised title given here.

Maybe let us debate whether or not the presented research does what the poster claims it does.

It's not the poster who makes the claim: "Team closes in on 'holy grail' of room temperature quantum computing chips" https://phys.org/news/2019-09-team-holy-grail-room-temperatu...

Tldr: It's a low loss nonlinear optical component, reducing the loss by a factor of 2.

Now explain like I'm five :)

They're trying to make a computer that computes using light that bounces around inside the computer. The more the light bounces around, the dimmer it gets, and the less effective it becomes at computing things. They figured out a way to make the light bounce around twice as long (and so be able to compute more stuff) before it gets too dim to work any more.

("Dim" isn't quite the right word, but you did say five.)

Damnit, now I have to learn Q#...I've been putting it off for more than a year but I guess I need to stay competitive. Well, actually, maybe this would be the right audience to ask; if I wanted to do some stuff with quantum, would you recommend Q# or is there a cooler language to use now?

I do know the MS guy largely responsible for Q#. He's an honest fellow and adamant that there is nothing like it. I've never worked with it. If you do get serious with it I'm sure the team would be very interested in hearing from you.

AFAIK the only "quantum computer" it currently interfaces with is LIQ𝑈𝑖⏐〉 (a simulator). http://stationq.github.io/Liquid/

Well, since I don't really have access to a real quantum computer yet, I'm ok with it just being on a simulator; I'm assuming that if/when quantum computers become cheap enough for consumer products, the MS team will probably work to make Q# support it.

What did that have to do with temperature?

Why is this the "holy grail"? Seems that room temperature quantum chips are not nearly as much of a big deal as, say, room temperature superconductors. You could keep a quantum chip in a special environment since they don't have to move around or span large areas.

Honestly, how many money-making initiatives do you expect to require programming a quantum-computer in the next 5 years? I can't imagine many people outside the upper tiers of a University lab or some highly-funded security arm at Google using this tech in the near-future? (Asking an honest question, not accusing)
