The central role of complex entanglement patterns, complex operators, and complex time evolution has been a recurring theme in these developments. The concepts quantifying these notions are rooted in the field of quantum computational complexity, the study of which tasks are easy and and which tasks are hard for a quantum computer. The basic idea of work at the interface of quantum complexity and quantum graivty is that computational complexity is a resource that can also be used to ensure the robustness of spacetime to perturbation by computationally-bounded agents. This robustness is an essential feature of holographic duality in gravity: complexity "hides" the inherent non-locality of quantum gravity from obvious experimental detection. This picture has opened a host of new questions in black hole physics, computer science, cryptography, condensed matter physics, and more. We aim to shed light on these connections... Thus, we bring together researchers in Quantum Information and..
