AI Summary

This work addresses the challenge of secure shared randomness distribution under energy-constrained adversarial jamming in arbitrarily varying channels by proposing a quantum communication protocol based on entangled two-mode squeezed states. For the first time within the standard optical communication framework, the scheme leverages quantum entanglement directly to enable secure randomness distribution without requiring external assistance, effectively countering active jamming that employs binary phase-shift keying and two-mode squeezed vacuum states. The proposed mechanism substantially enhances system stability and reliability under strong interference, establishing a new paradigm for jamming-resilient secure communication.

Abstract

Shared randomness is the central ingredient for stabilizing symmetrizable communication systems against arbitrarily varying jammers. Given the presence of the jammer, however, the question arises how this precious resource could have been distributed. Several works discuss the use of external sources for this task. In this work, we show, based on the most standard optical communication model, how the sender and receiver can employ entangled two-mode squeezed states to counter the jamming attack of an energy-limited jammer during the distribution phase when both the sender and jammer are allowed to use binary phase shift keying and two-mode squeezed vacuum states.
