Cue the bit about never needing more than 256 qbits

Rogaar t1_iuqbsxv wrote

What makes me always laugh is people think they are going to replace standard computers and we will all be walking around with quantum computers in our bags or powering our smartphones.

Everything I have ever read about quantum computers tells me they are built for very specific tasks and complex mathematics. The type of mathematics that takes super computers years to compute could be done in minutes or seconds with the right quantum computer.

I’ll come back to this post to laugh at you once I buy my first quantum home computer that will probably be left abandoned in the living room and used sparingly by my son to print his homework.

To be fair, there was a long gap between ENIAC and useful/inexpensive home computers. This, I think, is a similar jump in technology.

The point is that from the most basic standpoint, quantum computing isn't going to replace binary processors. It just does different things.

I'm not sure even a quantum computer can make printers work, thanks to Schrodinger's inkwell.

I think it could be a possible case of a problem that didn’t happen yet so we don’t need a solution right now.

No. Theres a reason why 80 since the first rockets flew that they are still only launched by large organizations with large financial backing. The technology is just mot compatible with personal use. Rockets are never going to be safe enough or efficient enough that you can park one in your backyard and take a joyride to space.

When I was a young teen, my potassium nitrate + sugar rockets made it to just shy of 4000m before I ruined my mother's kitchen and had to stop.

I guess my point is: Everything is already in civilian hands, but a residence is not suitable for working with extremely high (or low) energy densities.

No its not. Even the budget, edge of space options are far, far too resource intensive to ever be affordable.

The "but some people said cars wouldn't catch on" thing is a fallacy.

Since "normal" computers started off only being able to do basic calculations, perhaps the potential of quantum computers is vaster.

Perhaps it will create Facebook 2.0 and humanity can finally put down its spade and sword, take a breath and say "It is over. We've made it."

StalkMeNowCrazyLady t1_iuqm4h0 wrote

Exactly. Your OP is ignoring the fact that for ~40 years computers weren't considered to have a application or use in the life of an average person by tons of people, yet here we are. It may take 100 years but eventually the average person will have something more powerful than this particular quantum computer in their pocket everyday.

Harbinger2001 t1_ius643k wrote

That depends. There are some material science aspects of this that might not have a room temperature solution. I doubt We’ll be carrying around super-cooled computers.

ifuckedyourgf t1_iuw4t16 wrote

The point is that, for 99.9% of all use cases, a quantum computer is going to be vastly slower than an "equivalent" classical computer. Think of it as the computing equivalent of an idiot savant. Sure it'll factor numbers exponentially faster, but it's not like it'll improve the graphics of a video game.

Assuming it's even possible to mass produce miniaturized room temperature quantum co-processors suitable for consumer devices, it's not currently obvious (to me, at least) what that might be useful for. I'm not saying we won't ever find a use case, but I just don't know what that would be. Especially when we weigh the pros and cons against a cloud compute solution. My best guess is that there might be potential applications related to military/weapons technology and/or space travel, or other contexts without fast and reliable Internet access, but that's just speculation on my part.

More realistic to imagine a conventional machine with some quantum capabilities

phriot t1_iurznpq wrote

That was my first thought when I read the "not going to replace standard computers" comment. If/when room temperature quantum computers with sufficient miniaturization exist, they'll probably be co-processors for their optimal calculations. This would be like today's neural processing units that help with AI/ML tasks.

Unable-Fox-312 t1_iuu8i5i wrote

First I think we'll see QaaS. I think we'll see that regardless of its potential for consumer applications, but that's where the early building and testing for those would happen.

You may want to consider that an example of one of these “very specific tasks” is cryptography, or efficient machine learning algorithms.

Either of these would justify having one in our pocket.

Yeuph t1_iur2prf wrote

No, no it wouldn't. We have classical quantum proof cryptography.

Granted there always exists a chance some brilliant mathematician will discover math to break cryptography that thousands of other PhDs over the course of generations haven't been able to see or discover; with quantum cryptography you're relying on known laws of physics for unbreakable cryptography - so in theory it's more secure, but only trivially so and in practice there is no reason to suspect our quantum proof cryptography is vulnerable to Classical or quantum algorithms

Teamprime t1_iurfd7u wrote

The only classical quantum proof cryptography we know is immune to quantum attacks is symmetric, which is much less practical asymmetric. If someone invents an algorithm breaking current asymmetric encryption we may need to use quantum computing to create a new algorithm for that

nirehtylsotstniop t1_iutuayo wrote

haha yeah this rhetoric is so off point. I would play DA though that no-one with real skin in the game thinks that is the case. the inside-industry/academia opinion from my experience tends to be that Q-computation will NEVER replace classical, and hybrid algorithms have been the main advocacy from those groups for some time.

Pixel_Knight t1_iuuzuzl wrote

Does anyone actually think that? Outside of people who are completely ignorant on the subject of quantum computers?

I haven’t seen a single person or article ever make that claim anywhere.

Rogaar t1_iuv0hyo wrote

Plenty of people on social media seem to think so. Just read through the responses to my post.

People are comparing it to similar instances where years ago no one thought we would have computers at home as no regular person has any need for a computer.

They think it's just a natural evolution of technology that quantum computers will replace classical computers. Just like cars replaced the horse and cart.

Like your said, it's the ignorant people that don't understand there is a major fundamental difference.
