Entanglement-Assisted Classical Communication (EACC) aims to enhance communication systems using entanglement as an additional resource.
However, there is a scarcity of explicit protocols designed for finite transmission scenarios, which presents a challenge for real-world implementation.
In response, scientists have introduced a new EACC scheme capable of correcting a fixed number of erasures/errors. It can be adjusted to the available amount of entanglement and sends classical information over a quantum channel.
They have established a general framework to accomplish such a task by reducing it to a classical problem. Comparing with specific bounds, they identified optimal parameter ranges. The scheme requires only the implementation of super-dense coding which has been demonstrated successfully in experiments.
Furthermore, these results show that an adaptable entanglement use confers a communication advantage.
Overall, this work sheds light on how entanglement can elevate various finite-length communication protocols, opening new avenues for exploration in the field.
