Abstract
The first application of a quantum algorithm to Feynman loop integrals is reviewed.
The connection between quantum computing and perturbative quantum field theory is feasible due to fact that the two on-shell states of a Feynman propagator are naturally encoded in a qubit.
The particular problem to be addressed is the identification of the causal singular configurations of multiloop Feynman diagrams.
The identification of such configurations is carried out through the implementation of a modified Grover's quantum algorithm for querying multiple solutions over unstructured datasets.
