Quantum computers aren’t the next generation of supercomputers—they’re something else entirely. Before we can even begin to talk about their potential applic...

Until Quantum Computers come out of their alpha phase, it will certainly be a few years, but then the Gaming PC you have now will appear to you as an Abacus. Well, on the IBM website you can already try a Quantum Computer and even take a free course on programming with Qbits. https://quantum-computing.ibm.com (it’s free)

From what I understand, quantum computing isn’t going to replace classical computers. It’s simply good for a certain set of problems that can’t be computed efficiently using classical methods. So they will mostly expand the space of computable things.

Yes, at this time Quantum Computers are only suitable to handle large amounts of numerical and physical values, for example in meteorology and astronomy. But remember the use that the first computers had, before the PC, which at that time did not have other applications like these either. Although there are already Quantum PCs for sale, although at the moment they are not more useful than for experimental and educational purposes.

It’s possible to do all the same kinda of computations using both quantum and classical computers, but for a certain set of problems you just won’t get any benefit from having qbits. I expect future computers will end up having additional quantum cores the same way we have CPU and GPU right now. Different types of core will be optimized for doing different kinds of computations.

Yes, this is possible. There are also already considerable CPU / GPU improvement developments, using diamonds instead of silicon, thus even lowering costs with the current simple manufacturing of synthetic diamonds. The advantages are enormous, on the one hand due to the better electrical capacities of diamonds and on the other hand the much higher resistance to heat, which makes cooling unnecessary (a silicon chip is fried at 140ºC, the diamond supports more than 500ºC.

On traditional PCs, there is certainly still quite a bit of travel. Centuries since last Floppy Disk.

Yeah lots of exciting possibilities for new substrates after silicon. Gonna be fun times ahead. :)
