Since Einstein himself, unifying gravity with gauge theory has a long history. In this talk, I will first demonstrate how Einstein’s equation emerges from the quantum entanglement in CFT2. A profound relation between the cosmological constant and CFT2 entanglement entropy will be given. Surprisingly, the QFT RG equation turns out to be a geometric identity. Finally, I will provide a concrete and computable realization of the ER=EPR conjecture.
