What Does Quantum Computer Mean?
A quantum computer is a computer that operates on and/or incorporates aspects of quantum theory. Quantum computers are largely theoretical because of the massive amount of data needed to make them perform significantly, although some practical models have been developed, and current research is attempting to realize some of the theory of quantum computing.
Techopedia Explains Quantum Computer
One of the basic characteristics of quantum computing relates to the units used for data manipulation. In a conventional computer, these units are bits, which are binary values. In quantum computing and quantum computer models, the basic units are qubits, which can have a zero or a one value, or one of several additional values. The problem of representing these qubits in a data storage space is one of the essential barriers to practical quantum computer design.
