You realize quantum computing is ultimately just a few linear algebra operations right? There is no more magic in it than conventional neural network based models. Standard ML ethical frameworks are more than sufficient. 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.

>You realize quantum computing is ultimately just a few linear algebra operations right? 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…

A significant part of quantum computation is just a sequence of unitary transformations, represented by matrices. So essentially just a series of big matrix multiplications. The nonlinearity is introduced in the measurement. You have to repeat the calculation several times to build up a probability distribution.

> I was sceptical because 'AI' and 'quantum' seems to be used interchangeably and fits your regular snakeoil salestalk 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…

Agreed. All ethical frameworks should include Hindley-Miller type inference.

It is reasonable to temper one's skepticism about something like this based on whether the claiming party is willing to put their money where their mouth is. The greater likelihood is that they know something I might not (just speaking for myself as I don't know how much expertise you have in the quantum or AI fields).

Wave functions are just another type of vectors. Measurement (and collapse) is just an application of matrix diagonalization. It has its complications and its own beauty, but it is indeed just fanciful linear algebra (I work professionally on this).

I know next to nothing about all this but 'bottlenecks' don't worry me when talking about such a deep and ~nascent field. My first desktop had a whopping 4MB DRAM module in it .. we all saw the history of discrete computing manufacturing.

I distinctly remember reading an article in a scientific magazine promising the marvels of quantum computing in 95. Let's just say some progress since then certainly exists but it is quite not commensurate to the progress made on traditional computers. I'll not be surprised if we still talk about a "nascent field" in 50 years. (After all some still consider today programming to be so young that we don't really know h…

It might be more fair if you compare this to how long it took to move from Babbage's blueprints to something like ENIAC (more than a century?).

I think that BQP > P is not so important. Exponential advantage of known qalg vs known c_alg when the hardware is available is what's important.

that's what everyone says but imagine 10 years from now someone proves BQP < P. since that proof will entail a ptime reduction you'll immediately have a ptime shor's and etc.

We have a p time Shor's !

I don't think BQP<P makes sense... BQP <NP? I think you may be mocking me :(

Slightly tangential but how significant is O(sqrt(n)) speed up? Fast algorithms are slightly faster but intractable algorithms are still intractable?

It makes memory, not compute, the limit. 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.)

2^64 is hardly horribly insecure. Its on the edge of what a gigantic compute cluster can do. So its not secure, but hardly horribly insecure. Especially even if you can get a quantum computter working, its not going to be on the same level of operations that a million dollars in AWS credits will get you. At least not for a very long time.

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.

>"Already we run quantum computers that can perform calculations beyond the reach of classical computers" 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 t…

Ibm is a competitor in this space. Although there is some debate about google's claim, ibm is a very biased source as they have financial incentives to bad talk google.

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.
