# Gravity from quantum information

@article{Lee2013GravityFQ, title={Gravity from quantum information}, author={Jae-weon Lee and Hyeong-Chan Kim and Jungjai Lee}, journal={Journal of the Korean Physical Society}, year={2013}, volume={63}, pages={1094-1098} }

We suggest that the Einstein equation can be derived from Landauer’s principle applied to an information erasing process at a local Rindler horizon and Jacobson’s idea linking the Einstein equation with thermodynamics. When matter crosses the horizon, information on the matter disappears, and the horizon entanglement entropy increases to compensate for the entropy reduction. The Einstein equation describes an information-energy relation during this process, which implies that entropic gravity…
