It is believed that the message was sent from Nazi-occupied Normandy in June 1944. The encrypted message has been sent to the UK Government Communications Headquarters to be deciphered, so far without success. The amount

Decoding Quantum Computing

Simon Watson demystifies the complex world of quantum computing Quantum computers are regularly heralded as the future of computing, harnessing the power of atoms and elementary particles to perform calculations that today’s computers could only dream of. Quite how this remarkable feat is achieved is either complicated with jargon such as ‘qubits’, ‘superposition’ and ‘entanglement’ with no further description, or dismissed as too complicated for a layman. This article aims to explain how
