The holographic principle states that quantum gravitational theories can be described by quantum theories without gravity in one less spatial dimension. We will give a brief overview of holography, focussing in particular on explaining the holographic dictionary that relates gravitational physics to a lower dimensional quantum theory. Two corollaries of holography will be explored: the relationship between the holographic spacetime and quantum entanglement, and the use of holography to characterise gravitational waves in cosmological contexts. The link with quantum entanglement leads to interesting real world applications, including insights into quantum error correction and quantum machine learning.
