# Bounds on Quantum Information Storage and Retrieval

@article{Dvali2021BoundsOQ, title={Bounds on Quantum Information Storage and Retrieval}, author={G. R. Dvali}, journal={arXiv: High Energy Physics - Theory}, year={2021} }

We present certain universal bounds on the capacity of quantum information storage and on the time scale of its retrieval for a generic quantum field theoretic system. The capacity, quantified by the microstate entropy, is bounded from above by the surface area of the object measured in units of a Goldstone decay constant. The Goldstone bosons are universally present due to the spontaneous breaking of Poincare and internal symmetries by the information-storing object. Applied to a black hole… Expand
