Quantum Paradox Experiment May Lead to More Accurate Clocks and Sensors

By IQT News posted 21 Oct 2019

(ScienceDaily) More accurate clocks and sensors may result from a recently proposed experiment at the University of Queensland, linking an Einstein-devised paradox to quantum mechanics. A physicist said the international collaboration aimed to test Einstein’s twin paradox using quantum particles in a ‘superposition’ state.
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.
“The twin paradox is one of the most counterintuitive predictions of relativity theory,” Dr Zych said. “It says that time can pass at different speeds for people at different distances to an enormous mass or travelling with different velocities.
“The idea is to put one particle in superposition on two trajectories with different speeds, and see if a different amount of time passes for each of them, as in the twin paradox. “If our understanding of quantum theory and relativity is right, when the superposed trajectories meet, the quantum traveller will be in superposition of being older and younger than itself.
