I mean, that's literally how research works. You make small discoveries and use them to move forward.
What's to research? A fucking abacus can hold data longer than a goddamn hour.
Based take.
You disrespect the meaning of based
He meant base
Obvious troll is obvious
Must be the dumbest take on QC I've seen yet. You expect a lot of people to focus on how it'll break crypto. There's a great deal of nuance around that and people should probably shut up about it. But "dime stuck in the road is a stable datapoint" sounds like a late 19th century op-ed about how airplanes are impossible.
Not to mention that quantum cryptography has found ways to prevent that already.
The internet is pointless, because you can transmit information by shouting. /s
AND I can shout while the power is out. So there!
Are you aware that RAM in your Computing devices looses information if you read the bit?
Why don't you switch from smartphone to abacus and dwell in the anti science reality of medieval times?
You're describing how ancient magnetic core memory works, that's not how modern DRAM (Dynamic RAM) works. DRAM uses a constant pulsing refresh cycle to recharge the micro capacitors of each cell.
And on top of that, SRAM (Static RAM) doesn't even need the refresh circuitry, it just works and holds it's data as long as it remains powered. It only takes 2 discreet transistors, 2 resistors, 2 buttons and 2 LEDs to demonstrate this on a simple breadboard.
I'm taking a wild guess that you've never built any circuits yourself.
And you would have been there shitting on magnetic core memory when it came out. But without that we wouldn't have the more advanced successors we have now.
Nah, core memory is alright in my book, considering the era of technology anyways. I would have been shitting on the William's Tube CRT Memory system..

Though in all fairness, at the time even that was something of progress.
Doubt.
Core memory loses information on read and DRAM is only good while power is applied. Your street dime will be readable practically forever and your abacus is stable until someone kicks it over.
You're not the arbiter of what technology is "good enough" to warrant spending money on.
Core memory is also designed to accomodate for that and almost instantly rewrite the data back to memory. That in itself might be a crude form of 'error' correction, but it still lasts way longer than an hour.
Granted that quantum computers are a different beast of their own, how much digital data does a qbit actually store? And how does that stack up in price per bit comparison?
If they already know quantum computers are more prone to memory errors, why not just use reliable conventional RAM to store the intermediate data and just let the quantum side of things just be the 'CPU', or QPU if you like?
I dunno, it just makes absolutely no sense to me to utilitze any sort of memory technology that even with error correction still manages to lose information faster than a jumping spider's memory?
I'm taking a wild guess that you completely ignored the subject of the thread to start an electronics engineering pissing contest?
Do you really trust the results of any computing system, no matter how it's designed, when it has pathetic memory integrity compared to ancient technology?
That is not a product. This is research.
And that it looses data after merely a few milliseconds if left alone, that to account for that, DDR5 reads and rewrites unused data every 32ms.
Are you really comparing a fucking abacus to quantum mechanics and computing?
Yes, as far as memory integrity goes anyways. Hell, even without an abacus, the wet noodle in my head still has better memory integrity.
Don’t feed the trolls.
they are baiting honest people with absurd statements
They are shaking some informative answers out of literate people so I’m getting something out of it :D
True
Russian election interference money dried up and now they're bored
Absurdly ignorant questions that, when answered, will likely result in people knowing more about quantum computing than they did before.
And if it stopped there, we'd all be the better for it :)
Welp, quantum computers have certain advantages (finding elements in O(sqrt(n)) time complexity, factorizing primes, etc). The difficulty is actually making everything stable because these machines are pretty complex.
