Transmitting Correlation for Data Transmission over the Bosonic Arbitrarily Varying Channel

2026-03-02

AI Summary

This work addresses the critical challenge of securely distributing shared randomness to ensure communication stability in bosonic arbitrarily varying channels under the presence of energy-constrained adversaries. The authors propose a novel approach wherein the transmitter actively generates and transmits classically correlated thermal light or entangled two-mode squeezed states. By employing only homodyne detection and adhering to strict power constraints, this method enables interference-resilient distribution of shared correlations without relying on any pre-established external common randomness. For the first time in such channel models, the scheme leverages endogenous correlation resources to effectively counteract adversarial jamming, substantially enhancing system robustness. This paradigm shift offers a promising pathway toward secure communication under stringent physical constraints.

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 either classically correlated thermal light or entangled two-mode squeezed states created at and transmitted by the sender to counter the jamming attack of an energy-limited jammer during the distribution phase. Both sender and receiver are only allowed to use homodyne detection in our model, and the sender has to obey a power limit as well.
