(Twisted Sifter)   Unlike subby, who can barely complete a full week's work in a month, this quantum computer completed 9000 years' worth of work in 36 years. No wait, make that 36 seconds. **Re-reads TFA** HOLY CRAP 36 Microseconds. Say goodbye to strong passwords   (twistedsifter.com) divider line

So does P = NP or not?

But can it run Crysis on full settings?

The computers we are used to use binary (0, 1) and quantum computers use what is called qubits (0, 1, both).

And yet we still screw up how to handle null values...

This is why intelligence agencies around the world have been saving encrypted communications between parties of interest.  At some point, may it be the discovery of a weakness in the encryption or the ability of quantum computers to brute force at astonishing speeds, they'll find a way to crack it.

It's a definitive maybe.

BitwiseShift: Bitcoin mining all done in five.


Only if quantum computers are more efficient than classical computers at running the Bitcoin calculations.  That's not always the case.

If so, then I expect someone to come up with a new cryptocoin with a proof of work calculation that can only be done quickly on quantum processors.

And thus QuCoin was born.

Did someone run Doom on it?

Chief Superintendent Lookout: Did someone run Doom on it?


I'm gonna laugh so farking hard if quantum computers turn out to be the only things that won't run Doom. And that's just the kind of joke the universe might play.

"The UK Ministry of Defence purchased its first quantum computer in order to run tests, but it could be years before we know how or when they'll be used regularly."

Or possibly 36 microseconds, depending on how we look.

Bitcoin (and most other blockchains) use SHA-256, which is definitely vulnerable to a sufficiently large quantum computer.

I should clarify - that's for on-chain encryption, not mining.  But if you can crack the wallet keys, nobody is going to bother mining

Quantum computer produces quantum sampling results much faster than non quantum computer. Rick Romero with all the details at 5p.

This article was even worse than all other quantum computing articles because it made no mention of all the crazy things quantum computers will do for us in the future, including making our beds and tucking us in at night.

Sure, but do you trust the algorithm to sort it properly?

Imagine clippy: It looks like you got a lot of porn. Would you like me to help you sort that?

AHA! You have discovered the next step in quantum computing!

Four bits

Some of it is bad code, other is human error:

With loose comparisons on PHP, I've been using all three of these already/

Hop into the community Discord, you don't want to miss your opportunity to get in on the ground floor of this breathtaking moment in history.  Once you're whitelisted, you'll get a full asset deck to fully explain the tech and the position to anyone who is interested in buying in on history.

What if you use a quantum computer to create the encryption? Huh? Boom! Got you! I so smart.

Based on historic public funding levels, and current public funding levels, it's likely SHA-256 hash functions (including AES/RSA) are already insecure to one or more US national security agencies.  G7 governments tend to stop funding science once significant breakthroughs with obvious military application are close, and instead pursue topics more securely.

The last ten years of consumer computing has had a strong focus on cracking SHA-256. Called the Blockchain.

Just last week, my PM asked me to solve a problem that would make 12 billion years and about 3 exabytes of storage. If we can get our hands on one of these, it could take care of part of the problem.

CPU gets faster, IO stays the same.

Data in, data out: simply making one section faster doesn't make all faster.
