A qubit is the quantum equivalent of the 'bit', which can have the values, or 'states' of zero or one. However, because of their quantum nature, qubits can be in both states at once, due to a property called entanglement, the "spooky action at a distance" so disliked by Einstein. It's this remarkable property that gives quantum computers their huge processing power, such as the ability to crack all encryption schemes based on classical methods. If only mankind could build them. Quantum computers are still very much in an embryonic research phase and have been stuck there for decades, due to the difficulty of producing and working with entangled particles. The best that scientists have been able to do so far is to entangle just a few particles at extremely low temperatures, to reduce thermal noise corruption, to create qubits and research their behaviour. Now, it looks like mankind is a tiny step closer to building such quantum computers and this is where diamond comes in.
