The technology carries major national security implications because quantum computers potentially could break traditional internet security programs or other codes.

Developing viable quantum computers has proved to be hugely challenging because they rely on superconductivity that can only be achieved in temperatures close to absolute zero.
Any instability in the qubits, for example from vibrations, can lead to ‘noise’ that causes calculation errors and undermines a quantum computer’s power to solve problems.

Earlier this month, IBM announced it was joining forces with a German research institute to explore the potential of quantum computing, backed by a government plan to invest $717million over two years in wider research in the field.
