I mean what software would be made to actually use this that the average consumer would want to download, there's really nothing. It'd be like having a computer that you would never have to replace the CPU, ever? How much heat would something like this put off? |
No because it relies on quantum physics there is a degree of uncertainty in any calculation that you do with a quantum computer so you basically have a CPU that can work out really complicated things instantly but for every day things you would get math errors that cause all sorts of problems.
For example the on a nomal computer will always give you 10 / 6 = 1.666666666666667, a quantum computer might give you 1.666666666666666 and 1.666666666666668 and 1.666666666666667. Then the possible anwers would be quickly checked by working back from the possible answers. The advantage of a quantum computer is that in the same time it could make that calculation it could also work out the average temperature per hour of a location using 20 years of data for a sensor that records the tempreture every 10 minutes (an increadibly large dataset) or super complex mathmatical functions. Things that would take a long time on an ordinary CPUs. Of course all of this is theoretical, but a quantum computer is not just a really fast version of a normal CPU it is a totally different kind of computing.
Also a quntum CPU wouldn't just be able to do any calculation instantly, a 10-qubit quantum computer is not very useful a 100-qubit could do more, etc.
