Nonlocality-Assisted Enhancement of Error-Free Communication in Noisy Classical Channels
Kunika Agarwal, Sahil Gopalkrishna Naik, Ananya Chakraborty +5
The zero-error capacity of a noisy classical channel quantifies its ability to transmit information with absolute certainty, i.e., without any error. Unlike Shannon's standard chan…
