Quantum Computing - Hype vs. reality | Field Notes

As the race to build the world's first truly useful quantum computer intensifies, so too does the need for clear-eyed assessment. This Field Notes episode brings in the Google Quantum AI team to help answer a few fundamental questions to drive understanding of its impact now and in the future.

For a video called 'hype vs. reality' this video has a lot of elements from the quantum computer hype playbook.

[ormoran]

Feels like you are trying to create more hype instead of describing what quantum computers are like today

[sodiumfluoridel]

Surely a giga corporation with a monetary insentive to produce hype will give a good faith and accurate portrayal of what is hype and what isnt!

[Special]

"very niche applications" is the keyword. so far there are maybe 15 algorithms found for quantum computers after like 60 years of research

[SankhaSubhraBakshiexists]

Ok got the hype part. Where's the second part?

[giandomenicopanettieri]

this video is meant to bias you more toward hype. A brief outline: 
1. we start from "we have a quantum computer under reserch"
2. we evolve toward "in 10 years we will have the first error corrected quantum computer with 100k qubits" 
3. we present cool applications with catchy names like "fusion", "RSA crack" etc. trying to shadow at best classical computing
4. finally the cycle repeats since we were wrong 10 years ago as we need 1 million qubit that we will develop in the next 10 years.

I can understand the marketing behind this, but hype vs. reality will be really discussed when you will finally talk about the sate of the art technology that quantum computers are using, rather than jumping straight to the applications that there might be in 10 years. 
To understand reality I need to understand decoherence time of transom qubit ( why don't you explain to the audience this, with some Ramsey fringe plot), how it get worst as we scale the quantum processor, how we need to cool down the environment to insane temperatures, and so on. But yes, keep inflating the ballon.

With this comment I don't want to be disrespectful toward physicists that are working on this as I know that they are doing their best, but my point is that companies are a bit delusional on this topic. Only who is able to understand, face and talk about problems can takle them with cunning. But now a days it is more important to attract money rather than minds.

All this technology and no one has fixed the Bookmarks bar in Chrome closing every time you move a bookmark! 😉

I salute to all the researchers researching quantum computing in Google

[aarav]

Quantum computers will always be a decade away from the present ...

[naninano]

I have this one guy at watercooler who keeps bringing up decoherence limit or whatever, i think he is convinced that as size of quantum system grows, decoherence grows exponentially (same rate as projected theoretical computational power) and chance of getting a useful result becomes as unlikely as getting one from a classical computer. He is convinced this undiscovered law of nature exists. And I start to see his point.

Of course it's clickbait, it's Google reporting about Google 😂😂😂

[garretts]

It’ll be super fun when AI and quantum are combined. It’ll take one second for it to figure out we are not worth keeping around and how to eliminate us all. Super fun! Thanks guys!

[paalhoff]

Q: «Does quantum computers even exist yet?» A: «Gulp… ehhhh… well… yea kind of»

[AaTahya]

So... It's both useful & useless at the same time? Or is it all hype but also all real in its superposition?

[bhaveshsuthar]

Hype > Reality in the video.
Precise technical Videos on technology are relatively scarce on youtube, but the good ones is like priceless information

[serg]

Should have talked about CAT qubits and LDPC codes. Once they’re instituted it’ll make processing much more capable

[ibrahimkuyumcu]

Funny. As if Google has not endeavoured in the hype?

[louistech]

I think this will be in our lives in 25 years . I think AI and machine learning will actually propel our current computers to the next step . 😊

Probably a big reason why this became so heard of was, Information Operations by the United States.

In trying to protect information elsewhere, someone along the lines thought quantum computing was probably a good option for explaining things like electromagnetic warfare on the American public.

Simulation in many areas of manufacturing are and have been helping with complex design issues for several years now.
See what the future has in store for more improvements
