Sending quantum information through a chain of qubits, like energy through a Newton’s cradle, could be the key to faster operations, and take quantum computing to the next level. The quantum Newton’s cradle design shows how a laser can be used...

The mystery of the possible quantum nature of gravity could be solved with lasers – a major contrast with the conventional approach of using masses, say ANU physicists. Quantum mechanics’ success in describing light and particle behaviour...
