We need to seriously think if our systems/society are even remotely ready for this.
I'm far more scared when tech-bros like Musk land on Mars and contaminate stuff we might not even be able to detect yet.
>Willow’s performance on this benchmark is astonishing: It performed a computation in under five minutes that would take one of today’s fastest supercomputers 1025 or 10 septillion years. If you want to write it out, it’s 10,000,000,000,000,000,000,000,000 years. This mind-boggling number exceeds known timescales in physics and vastly exceeds the age of the universe. It lends credence to the notion that quantum compu…
But to put into context, these numbers are likely accurate, but represent the time it would take for a very naive classical algorithm (possibly brute-force, I am unsure).
For example, the previous result claimed it would take Summit 10,000 years to do the same calculation as the Sycamore quantum chip. However, other researchers were able to reproduce results classically using tensor-network-based methods in 14.5 days using a "relatively small cluster". [1]

> Willow performed a standard benchmark computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion years — a number that vastly exceeds the age of the Universe. What computation would that be? Also, what is the relationship, if any, between quantum computing and AI? Are these technologies complementary?
"Also, what is the relationship, if any, between quantum computing and AI? Are these technologies complementary?" AI is limited in part by the computation available at training and runtime. If your computer is 10^X times faster, then your model is also "better". Thats why we have giant warehouses full of H100 chips pulling down a few megawatts from the grid right now. Quantum computing could theoretically allow your…
> It lends credence to the notion that quantum computation occurs in many parallel universes, in line with the idea that we live in a multiverse I see the evidence, and I see the conclusion, but there's a lot of ellipses between the evidence and the conclusion. Do quantum computing folks really think that we are borrowing capacity from other universes for these calculations?
I'm upset they put this in because this is absolutely not the view of most quantum foundations researchers.
It could be that we are borrowing qbit processing power from Russel's quantum teapot.
> It lends credence to the notion that quantum computation occurs in many parallel universes, in line with the idea that we live in a multiverse, a prediction first made by David Deutsch. Processing in multiverse. Would that mean we are inyecting entropy into those other verses? Could we calculate how many are there from the time it takes to do a given calculation? We need to cool the quantum chip in our universe, ho…
What if we are? And by injecting entropy into it, we are actually hurrying (in small insignificant ways) the heat death of those universes? What if we keep going and scale out and in the future it causes a meaningful impact to that universe in a way that it's residents would be extremely unhappy with, and would want to take revenge? What if it's already happening to our universe? And that is what black holes are? Or…
DE is some sort of entropy that is being added to our cosmos in an exponential way over historic time. It began at a point a few billion in to our history.

Probably just research on quantum computers? I don't think it's big enough to let you solve any practical problems, but maybe someone can correct me
IF (and that's a big if) that's true then it means they can factorize number into primes with this quantum computer and break encryption.

Not sure what you mean by the "that" when you say "if that's true", but there is nothing in this thread or by google that is anywhere close to breaking encryption.

This comment reminded me of the TV show I've been recently watching on Netflix, Pantheon. It's about a different technical breakthrough (I don't want to put any spoilers), but it's also something that completely alters society, no security is able to deal with that new technology, first thing that happens is that the technology is weaponized... etc. Idk enough about quantum computing to even understand this... but a…

In order to evolve, forbiding evolution is the wrong path. Just use and study and learn from new things and accumulate experience is the way to go.
