An article 'Recycled photons set fresh quantum computing record'has been published in the New Scientist.
Dr Anthony Laing and colleagues from the Centre for Quantum Photonics have used recycled quantum bits, or qubits, to carry out a quantum calculation known as Shor's algorithm on a larger number than ever before.
