A framework for separating dephasing from decoherence in matter-wave Bell interferometers
S. Kannan, Y. S. Athreya, X. T. Yan +2
Matter-wave Bell interferometers provide a sensitive probe of mass-dependent decoherence in entangled quantum systems. The degree of entanglement is obtained from the Bell-correlat…

Proposal for a Bell Test with Entangled Atoms of Different Mass
X. T. Yan, S. Kannan, Y. S. Athreya +2
We propose a Bell test experiment using momentum-entangled atom pairs of different masses, specifically metastable helium isotopes 3He* and 4He*, though the method extends to other…

Bell correlations between momentum-entangled pairs of atoms
Y. S. Athreya, S. Kannan, X. T. Yan +4
Nonlocal entanglement between pair-correlated particles is a highly counter-intuitive aspect of quantum mechanics, where measurement on one particle can instantly affect the other,…
