what is quantum computing and how does it work
A quantum computer is a computer design which uses the principles of quantum physics to increase the computational power beyond what is attainable by a traditional computer. Quantum computers have been built on the small scale and work continues to upgrade them to more practical models.he ability of a quantum computer to perform multiple computations simultaneously (or in parallel, in computer terms) is called quantum parallelism). The exact physical mechanism at work within the quantum computer is somewhat theoretically complex and intuitively disturbing.
