WHAT IS A QUANTUM COMPUTER?
At the heart of quantum computing is the quantum bit, or
qubit, a basic unit of information analogous to the 0s and 1s
represented by transistors in your computer. Qubits have
much more power than classical bits because of two unique
properties: they can represent both 1 and 0 at the same time,
and they can affect other qubits via a phenomenon known as
quantum entanglement. That lets quantum computers take
shortcuts to the right answers in certain types of calculations.
