Quantum Computers - Quantum Computing
Quantum computing relies on qubits, bits that are held in superposition and use quantum principles to complete calculations. The information captured or generated by a quantum system benefits from the ability of qubits to be in more than one physical state at a time (superposition), but there is information decay in capturing the state of the system.
One point that will be immediately relevant to the discussion is that quantum computers are not universally better than classical computers as a result. A quantum computer can do a certain task better than classical computers, perhaps one that is impossible to do in any reasonable timeframe with classical computers.
