Quantum Contextuality Measurements on Mode-Entangled Neutron Beams

ORAL

Abstract

We present and discuss recent measurements [1,2,3] of quantum contextuality witness values for neutron beams mode-entangled in spin, position, and energy degrees of freedom. These measurements explicitly confirm the ability of entangled slow neutron beams to evade quantum decoherence in condensed matter and may help enable precision measurements with neutron beams to avoid certain classes of systematic errors.
