"Nature is quantum mechanical: The bonds and interactions among atoms behave probabilistically, with richer dynamics that exhaust the simple classical computing logic."
"Already we run quantum computers that can perform calculations beyond the reach of classical computers."[citation needed]

Yea this isn't true. Their 54 qubit machine can simulate random circuits pretty fast but
1) that's not at all useful and specifically contrived as a test of "quantum supremacy".
2) totally debatable whether it's actually out of reach:
>In the paper, it is argued that their device reached “quantum supremacy” and that “a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task.” We argue that an ideal simulation of the same task can be performed on a classical system in 2.5 days and with far greater fidelity

As far as point 1 goes, nobody ever claimed otherwise. Its just an arbitrary milestone. Walk before you run. Quantum supremacy is a step in the journey, not the destination. You make a hello world program before making actual useful programs.
I've seen a lot of criticism that DWave is only good at making hardware that's hard to simulate without doing anything useful with it. What's different here?
Also, what do you mean by "allegedly"? Aren't the basics of their hardware pretty well-understood, or do you think they're sitting on a secret classical algorithm that's fooled external researchers (including Google) into believing that they've demonstrated multiqubit entanglement?
I'm well aware - doesn't mean they're not right.
>You make a hello world program before making actual useful programs.
how hilarious would it be if some chip manufacturer bragged about the performance of a hello world on their chip...?
That was my first take - and akin to saying "quantum intelligence" which just reeks of marketing on a synergy overdrive mission.
Of course they are just using quantum hardware/software approach towards AI type problems. So for me it may of been better to say Quantum Annealed AI. But then, as a campus name, it don't have that marketing ring going for it.
One question though that will arise down the line will be ethics, with a classical computer you can drill down and understand fully every bit of decision making if needs be. With a quantum computer, not so easy at all. Maybe possible that they create a good quantum AI system but equally at the same time it is also an evil AI system, only that they observe only the good as that is what they are looking for.
Philosophy is going to have a whole avenue of debate over this in years to come and who knows - AI psychology might be the future job we never expected to happen.
Adding "quantum" simply means speed ups for a few specific types of operations. You are not going to get an AGI with the current state of the art in quantum computing.
More specifically, are they better than the ones from "neuromorphic" chips like Intel Loihi?
Quantum systems have wavefunctions though, which collapse to a state. And before collapse, these can interfere. The math of this involves way more than normal linear algebra. Especially when you consider the things we've simplified away -- e.g. how exactly the wave function collapses. (We just say it's 'abrupt' and kinda leave it there. But it's possible this has implications for quantum computing, once we think in quantum theory terms rather than CS.)
Agreed. All ethical frameworks should include Hindley-Miller type inference.
It halves the exponent on the number of operations. 2^128 - reasonably secure by todays standards! 2^64 - horribly insecure.
(CAVEAT: where the speedup is applicable, which is often hard.)
Besides,in most places where that is an issue, its trivial to switch to 256bit algorithms
> (CAVEAT: where the speedup is applicable, which is often hard.)
Grover's algorithm has pretty wide applicability. Its the exponential speed ups like shor's algorithm that have super limited applicability.

As I understand it loading classical data into a quantum computer - into quantum ram - is a big bottleneck. So running a QNN over a picture of a cat can't give a speedup vs. running it on a classical machine. Is this wrong HN?
I haven't found a result showing QNN's do offer strong speedups for training or testing - I have found papers saying it looks good - but I haven't found the result. I think this may be a literature search fail by me though.
For generalisation I have seen papers claiming that there will be better generalisation with QNN but I have failed to understand this result and do need to work harder!
I also believe that the most promising algorithm for quantum ML (HHL) has been "dequantized" I think that Grover's and QMC are pretty secure but also only quadratic in speed up (I say only - this is because that means there is a window of quantum advantage that may or may not be useful before the quantum algorithms fall off a cliff as well.
Ok - I need to understand this stuff for real, so please shoot me to bits !
Throwing AI on the research campus does help focus what researchers will do there - e.g. research algorithms which can plausibly improve training, inference, and generalization of neural networks/ML models. Rather than researching other more "practical" QC applications such as cryptography.
Is there any known quantum algorithm that gives a speedup over classical algorithms? I don't mean "call Grover as a subroutine" during your standard classical optimization algorithm.
It is as of yet unknown whether quantum computers are more powerful than classical computers; there is no proof that BQP is strictly bigger than P. There is oracle separation but that's not the same thing.
I don't think BQP<P makes sense... BQP <NP? I think you may be mocking me :(
Also a bunch more.
Tech is either esoteric or exoteric. It either is a thing for only experts to understand and use and put to use, or it is something illuminating, something shareable, is a conveyable experience. Quantum AI combines two of the most opaque, hard to understand fields to make something whose prestige in large part rests upon it being entirely indecipherable to 99.9999999% of humanity.
To which I just keep wanting to say, can we please make personal computing a thing again?
Are "sustainable energy", "reduced emissions to feed the world's growing population" and "unlocking new scientific discoveries like more helpful AI" goals that Google is currently working towards?
Regarding the need to feed "the world's growing population", note that absolute increase in global population per year has levelled off for several decades and may even be decreasing:
That should be interesting. There's been some good physics from there. Flash LIDAR came from Advanced Scientific Concepts there.
UC Santa Barbara is Hollywood's vision of a college. Everyone is good-looking and the college is right on the beach.
It would be great if the audio clips had the standard seek bar with the ability to pause/play. Perhaps when I scroll up or down to a section, pause the current audio clip. Then resume playing it when I come back. But also allow me to seek around. Rather than just restarting from the beginning. Because these clips are several minutes long and I am given no indication of their length.
Currently all I can do is either continue listening for an unknown amount of time, or go to the next/previous section and completely lose my progress.
We intended for each clip to be much shorter, which might have diminished the importance of a feature like the one you suggested. Even after we cut down the audio we got from the team, there was still a lot of great exposition, but not enough time to revisit that part of the design.
That said, I'll be sure to share this with the team.
Go watch it!
I guess she was in at least one episode of ST:PIC but I haven't followed up on that.
Just handwave in front of your Quantum AI HAL-9000 and it will imagine a create software for you!
