The ER=EPR connection is the conjecture[1] that in a theory of quantum gravity, the existence of entanglement always implies the existence of a wormhole in the quantum geometry. ("ER" refers to Einstein-Rosen bridge, an old name for wormhole, and "EPR" to Einstein, Podolsky, and Rosen, who wrote a very early paper on entanglement.)
