The possibility of quantum simulation of problems from high-energy physics has been postulated, and tensor network algorithms are taking off in that area as well, providing novel computational tools to study now also strongly interacting systems un­der extreme conditions typical for high-energy physics problems. Tensor networks have also been used in the explicit construction of models displaying the basic features of the anti-de Sitter/confor­mal field theory (AdS/CFT) correspondence.

Concepts from quantum information theory such as scrambling or information loss are giving novel perspectives to problems in quantum gravity. New theories describing black hole physics build upon analogies between black holes and critical quan­tum systems known from condensed matter or atomic physics. Furthermore, technologies devel­oped in atomic and laser physics during the last thirty years have led to extremely precise spec­troscopic techniques.

These are used, for exam­ple, to test fundamental theories in physics in table top experiments by, for instance, employ­ing the electric dipole moment of the electron, or by measuring the effective radius of the proton with unprecedented precision.
