Our supercomputers and their processors will soon be obsolete. The new type of processors for computers are here to come. Quantum computers are computers that work on quantum processors.
A quantum processor is a much more powerful processor than the semiconductor one. Therefore, an equal sized version of quantum computer can perform a huge number of tasks more than an ordinary processor computer.
Quantum computers can be capable to do mammoth processing operations, which also take lot of time to perform now and some which require more powerful supercomputers.
