"Quantum computers promises to perform certain tasks that are believed to be intractable to classical computers. Boson sampling is such a task and is considered as a strong candidate to demonstrate the quantum computational advantage. We perform Gaussian boson sampling by sending 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random matrix—the whole optical setup is phase-locked—and sampling the output using 100 high-efficiency single-photon detectors. The obtained samples are validated against plausible hypotheses exploiting thermal states, distinguishable photons, and uniform distribution. The photonic quantum computer generates up to 76 output photon clicks, which yields an output state-space dimension of 1030 and a sampling rate that is ~1014 faster than using the state-of-the-art simulation strategy and supercomputers."

Don't really care how powerful it is. It is something that won't be possible in our life time probably. Not in a desk top form anyway. Well probably will since everything will move to the cloud sooner or later and we will be forced to just use dumb terminals at home.

Apparently if it is possible we will not necessarily know about it (could very well occur in a private lab company like Google) and because they could end up being particularly good for non exact calculation of the AI type (finding path and so on) that is used by a lot of what smartphone/facebook do, it could make them even better at capturing attention and changing what we do, it could potentially be an important subject of society.

The bad thing is ... this video is a joke ... while this quantum stuff is not. And that just makes it worse, lol.

Seeing as there seem to be only 10 or 20 people in the world that claim to understand this stuff for real.... how do the rest of us know its not the Quntoencabulator ?

Perhaps those 10-20 people can't stop laughing when we aren't in the room.

Plot twist, the quantum computer is actually a time machine so it actually takes it 2.6 billion years to compute then sends the result into the past so it appears it only took 4 mins.

An engineering friend of mine ,who helped build a Candu Reactor ,now working for a startup doing parallel work to this,says its really just snake oil,for execs to get their claws into what he calls a bottomless pit of Venture Cap funding from 5 eyes.
 
Did I miss it, or did they neglect to say what the actual problem was? Or the results they got? Or how they know the results are correct?
 
"Photons are sent into the network (one at each input) and exit in a state that is randomly chosen from all possible states. In less than four minutes, the researchers had obtained results that they estimate would take a fast classical computer about 2.5 billion years to calculate."

All built by slave PhD students striving to get a PhD where their only job hope is a Barista at Starbucks or teaching a class at a university that collectively are becoming some of the worlds most hated institutions due to thier cancerous politics.

We need to go back to the days when the best scientists didnt even care what a university was. Hard to get a grant, near impossible, unless you have a massive .edu behind your name. So many scientist at home but cant get funding. Buy hey these guys just made light bounce around a little bit. Cool.

Oh right and they got to meet thier publish or perish quota for the year.

It's called crowd sourcing... or venture capitalism (?:?) Elon Musk never got a PhD, and hell he's supposedly self taught... I mean he apparently read the book where Robert Goddard had plans for a vacuum tube transportation system that whisks people around and great speeds... then slapped his name on it and convinced other people to fund it all.
 
Don't worry, post-quantum cryptography will be here long before this stuff gets into the hands of bad actors.
