in 2010 Mark Van Raamsdonk suggested that quantum entanglement of degrees of freedom is responsible for the connectivity of spacetime. earlier this year Michał Dąbrowski, Michał Parniak, and Wojciech Wasilewski reported about a demonstration of the EPR paradox in a hybrid bipartite
the authors presented an approach based on spatial structure of light–atom entanglement, with a delay time of 6 μs between generation of entanglement and detection of the atomic state. should we use this type of setup between two sites, one on earth and the other on a baloon (~ 1 km higher), thereby extending the Pound and Rebka experiment; would we then be probing whether gravity interferes with quantum entanglement?
