A clock moving in superposition of different speeds would measure a superposition of different elapsing times — in a quantum version of the famous ’twin paradox’ of special relativity. Credit: M. Zych.
More accurate clocks and sensors may result from a recently proposed experiment, linking an Einstein-devised paradox to quantum mechanics.
University of Queensland physicist Dr Magdalena Zych said the international collaboration aimed to test Einstein’s twin paradox using quantum particles in a ‘superposition’ state.
