Quantum test of the equivalence principle for atoms in coherent superposition of internal energy states

Atom interferometers can be used in precision measurements and to test the fundamental laws of physics. Here the authors test the weak equivalence principle in the quantum regime with high sensitivity using a Bragg atom interferometer with rubidium atoms in their hyperfine states.
