A quantum computer is a hypothetical computer, which in theory
could produce a computer with a far higher processing capability
than the current binary based computing model. Hence the term "a
quantum leap". Simple put, the reason why a quantum computer
would process data faster: is that, unlike a binary computer, each
data unit in a quantum computer could be in more than "one"
place at a time and "think" / "process" multiple
"thoughts" at the same time. Of course, one data unit
in a quantum computer would be something totally different to one
data unit in a binary computer. The smallest piece of data in a
binary computer is termed a "bit", whereas in a quantum
computer - computer scientists - have referred to the smallest piece
of data as a "qubit" or "qbit".
