报告摘要：
Bell nonlocality is among the most fascinating and paradoxical phenomena exhibited by quantumsystems. Intriguingly, even though quantum correlations can be stronger than classical ones, they are still subject to certain constraints. A crucial question for the foundations of quantum theory is whether there exists a physical, operational principle that accounts for these limitations. The information principle is a physical principle designed to constrain nonlocality without relying on the fundamental assumptions of quantum mechanics and it is based solely on the axioms of information theory. IC principle states that the amount of randomly accessible data over a classical communication channel cannot exceed its capacity, even if the sender and the receiver have access to a source of nonlocal correlations. In this work, We obtained a tighter bound primarily through the following two changes: (a) Replacing the noise channel with the combined channel in the communication protocol and (b)Considering a concatenated protocol with k = 2.
