Can't wait to have one of these in my back-pocket in 20 years lol I love how fast tech evolution is.

What use would you have for a quantum computer?

That’s like asking 20 years ago “what use would you have for 32gb of RAM?”

Indeed we don’t. But based on the continuing exponential growth of humanity’s technological advancement it’s reasonable to assume that we’ll have some interesting use cases for mobile quantum computing two decades from now.

In the past 2 decades we went from basic Nokia to 5G LiDAR ARM smartphones.

But as per our current trend, we are moving towards a centralized (cloud) focused computing model. It would be logical to assume that any tasks that a normal person would do, that requires quantum computing, would be done in a centralized data centre with the input and the then the output being transmitted to a traditional computing interface that the person has access to

You want a use case for mobile quantum computing power? Here:

One problem quantum computing presents is that its computing potential overrules all current encryption mechanisms right? If your beautiful centralised computing solution can easily decrypt any data stream encrypted by conventional means then you’ll probably need an equally advanced solution to encrypt your data.

Another: a mobile running a 20-year-in-the-future graphics/physics game engine to simulate an AR reality over 10G internet together with 40.000 other players using the 20 different cameras in your phone that observe x-rays throughout microwaves while streaming to your 4D headset.

I’m certain there are mathmaticians and IT scientists out there who can elaborate on why this is/isn’t a bs use case. My point is that if I can come up with a potential use case in seconds while I’m cooking diner, then it’s plain dumb to assume that TONS of people won’t come up with actual use cases in the coming 20 years.

There is something of a trend of a pendulum swinging between centralization and decentralization in computing.

Mainframes where you had to physically sit at and perform batch processing eventually had time-sharing capability added via remote terminals. Centralization came back when we got PCs, which then gave way to having data available on the internet. Our phones became computers, and then fast mobile data connections let us shift applications and processing into the cloud.

If it's physically possible to have a quantum computer at home, or in our pocket, we probably will. If I had to guess based on how we do things today, I'd say that those quantum processing capabilities will probably be used for co-processing for very specific applications. Maybe quantum cryptography? And anything more general, or requiring a large amount of qubits, will be available via the cloud.

No it's not. 32gb of RAM would have been an improvement of your current system. A quantum computer isn't an improvement over a phone.

Why do you think that?

A quantum computer functions differently than a conventional computer. A quantum computer isn't better or faster at achieving tasks you'd do with your phone.

It wouldn’t be better at the tasks I do with my phone now. What do you know about the tasks I’ll be doing with my phone 20 years from now?

Cykablast3r t1_ivt58gc wrote

I can take a guess? What would the tasks be like that you'd have use for a quantum computer?

DILDOS_UNITED t1_ivu2q8m wrote

That wasn’t exactly a guess now was it?

I can think of a few and speculate from there. But I think it’s more valid to state:

The argument ‘what would you use it for’ is the exact same argument they made 20 years ago for why you’d need 32GBs of RAM in your pc. Well maybe 30 years ago, but exponential growth and all that.

What wasn't?

This argument is a false equivalence. Quantum computing isn't "same but more powerful" it's a completely different thing with a different use case. You're comparing cars to trains.

The essential difference between bits and qbits is the ability to represent superpositions. That’s basically ‘same but way, way, waaaay more powerful’. I’d absolutely love to have a supercomputer in my pocket and I can certainly think of some use cases that involve technology that doesn’t exist right now.

The best use case I can come up with right now is an advanced physics game engine that simulates physical reality by processing interactions between quantum particles. This would definitely be done best by a quantum gpu. Why would you? Why wouldn’t you? Why wouldn’t you stream all that data from a supercomputer in the cloud? Same reason I build my own desktop instead.

It’s very strange to me that you think people wouldn’t 100% build and find uses for a train in their pocket if they could. History has certainly shown otherwise.

No it's not. Not at all. qbits aren't more powerful than bits, they're completely different. A conventional computer would be far better suited for the tasks we already use it for.

Quantum computers aren't being developed as a replacement for conventional computers, they're being developed for things conventional computers can't manage, namely combinatorics. You don't need combinatorics in your daily life.

>It’s very strange to me that you think people wouldn’t 100% build and find uses for a train in their pocket if they could. History has certainly shown otherwise.

No it hasn't? I don't know anyone who owns a train. A car is much more useful.

That’s so funny because IBM’s website says they are more powerful. Whatever you say then chief. Not sure where you’re getting that they’re being made for fancy counting.. all I read is that this tech is amazing at advanced simulation and complex calculations. Literally no one but you is saying that conventional computers are ‘better suited’ to what we use them for. Other than the fact that right now these huge machines only have a few hundred qbits of course.

Yeah whatever mate, you do you. Time will tell I guess.
