Corridor of Madness

'The fundamental memory component of a quantum computer has been built for the first time using a string of atoms. This could offer a more reliable way to build a working quantum computer than other techniques, suggest researchers.

Quantum computers exploit the quantum properties of matter to perform calculations. While conventional computers use binary digits - or bits of information - in the form of electrical charge, quantum computers use quantum bits, called qubits.

And because particles can be in several states at once, qubits would allow huge numbers of computations to be carried out simultaneously - beyond the capabilities of a conventional supercomputer.' (New Scientist article)
