Descripción
Theoretical predictions at high-energy colliders are based on encoding the quantum fluctuations that occur at very short distances by Feynman diagrams. These diagrams are made up of interaction vertices and propagators, which in fact represent a quantum superposition of propagation in the two directions between two interaction vertices. Therefore, Feynman propagators can be identified with qubits. We analyse the consequences of this interpretation and how it can be exploited to derive a manifestly causal representation of scattering amplitudes, leading to achievable theoretical predictions in quantum field theory at very high perturbative orders.
