Proposal for a Bose–Einstein Condensate Based Test of Born’s Rule Using Light–Pulse Atom Interferometry
/en/research/publications/proposal-for-a-bose-einstein-condensate-based-test-of-borns-rule-using-light-pulse-atom-interferometry
Light-pulse atom interferometry with ultra-cold quantum gases is proposed and numerically benchmarked as a platform to test the modulo-square hypothesis of Born’s rule. The interferometric protocol…
