Google Acheives Quantum Supremacy
quote:

This could be the dawn of a new era in computing. Google has claimed that its quantum computer performed a calculation that would be practically impossible for even the best supercomputer – in other words, it has attained quantum supremacy.

If true, it is big news. Quantum computers have the potential to change the way we design new materials, work out logistics, build artificial intelligence and break encryption. That is why firms like Google, Intel and IBM – along with plenty of start-ups – have been racing to reach this crucial milestone.


...

quote:

The paper describes how Google’s quantum processor tackled a random sampling problem – that is, checking that a set of numbers has a truly random distribution. This is very difficult for a traditional computer when there are a lot of numbers involved.

But Sycamore does things differently. Although one of its qubits didn’t work, the remaining 53 were quantum entangled with one another and used to generate a set of binary digits and check their distribution was truly random. The paper calculates the task would have taken Summit, the world’s best supercomputer, 10,000 years – but Sycamore did it in 3 minutes and 20 seconds.



TL;DR - Google's quantum computer can do a task in 3 minutes that would take the largest supercomputer in the world 10,000 years to complete. And, no, I am not sure what framerate in Crisis it can achieve.

How will this affect porn? That’s usually how new tech gets measured.

And they will still adjust it to downgrade “fake news” in its computing calculations.

So they took and old super computer and put it up against a new faster one. Bunch of geeks.

Break this down further please. Define task as well. Sounds cool, but what do we gain?

AI

A primary application for quantum computing is artificial intelligence (AI). AI is based on the principle of learning from experience, becoming more accurate as feedback is given, until the computer program appears to exhibit “intelligence.”

This feedback is based on calculating the probabilities for many possible choices, and so AI is an ideal candidate for quantum computation. It promises to disrupt every industry, from automotives to medicine, and it’s been said AI will be to the twenty-first century what electricity was to the twentieth.

A quantum computer takes two particles (electrons or photons) and entangles them together to do calculations. A traditional computer bit is a 1 or a 0. With a quantum computer, a bit is a 1 and 0 at the same time. So instead of calculating X or Y, a QC can calculate X and Y at the same time. This results in an exponential speedup in various computing tasks (in some tasks, but not in others).

The military wants it because it can break (most) known cryptography, meaning we can spy on anyone who uses traditional crypto. I'm sure NSA would love to have a big fat QC in their basement. Even if the adversary invents quantum proof cryptography (already being worked on), NSA certainly has lots of old documents they'd love to decrypt. If you can decrypt a 10 year old Russian or Chinese document, this could still be highly relevant today for the intelligence agencies.

The private sector wants it because it can really help with research in chemistry, nuclear research, medicine, etc. We can simulate stuff really quickly with it. Instead of buying time on a massive supercomputer and waiting for a long time for a half-assed simulation, you can get a much better one in a much shorter time with a QC.

Quantum computing isn't a new idea. I believe people were discussing it in the 60's. The problem has always been an engineering one, sorta like nuclear fusion. In both cases we know theoretically it can work, but doing it is the hard part. Google is showing they are making progress in making it actually work.

These computers use a completely different type of processor that isn't bound by the limits of heat and speed that normal computers have. The way they work is pretty technical. They use quantum entanglement instead of simple electrical signals.

Long story short, quantum computing will make modern computers look like a fricking abacus by comparison.

You can think of it simply as a huge jump in processing speed, like no jump before in the history of computing.

Things like weather prediction, traffic control, drug/chemical development, AI and online security are some of the beneficiaries that have very obvious practical applications to our everyday lives.

Yes, so far. I believe they need liquid nitrogen and shite right now.

Again, there are a lot of parallels with nuclear fusion. In order to get energy from fusion, you need to do a lot of very hard engineering like containing the plasma ball in a magnetic field. That's why people want "cold fusion" which scientists in the 80's claimed they had (and was later found to be a fraud).
