Michelson-Morley Experiment for Electrons

 A new experiment conducted at the University of California at Berkeley used quantum information techniques for a precision test of a cornerstone principle of physics, namely Lorentz invariance.  This precept holds that the results of a physics experiment do not depend on its absolute spatial orientation.  The work uses quantum-correlated electrons within a pair of calcium ions to look for shifts in quantum energy levels with unprecedented sensitivity.   JQI Adjunct Fellow and University of Delaware professor Marianna Safronova, who contributed a theoretical analysis of the data, said that
