Researchers have announced a major breakthrough in the quest to build an effective quantum computer – a machine which could revolutionise everything from drug discovery to cancer treatments.

Quantum computers have ‘qubits’ instead of ‘bits’ of ones and zeroes – and qubits can be one, zero or both at the same time.

Creating an effective quantum computer could unlock unheard-of computing power, researchers believe – although some warn that the discovery could ‘break the internet’, with quantum machines able to break current encryption methods.

Researchers from the University of Sussex and Universal Quantum showed off this month that qubits can directly transfer between quantum computer microchips and demonstrated this with record-breaking speed and accuracy.
