Quantum time inversion to prevent DDoS attacks: A potentially realizable TENET technology

An effect known as time inversion was introduced in Christopher Nolan's film TENET, and here we demonstrate that such an effect exists for quantum information. We do this by investigating the von Neumann entropy of experimentally realized photons that are entangled in time. Using these findings, we design a technology called a Turnstile and apply it to detect Distributed Denial-of-Service (DDoS) attacks in quantum networks. Pragmatically, our work can be viewed as formulating the quantum analogue of the Shannon entropic DDoS detection systems used in classical networks.
