The Echod protocol is a quantum key distribution (QKD) protocol that aims to establish a secure communication channel between two parties using entangled quantum states. In the context of the classical CHSH inequality, the Echod protocol violates the inequality, indicating the presence of entanglement between the quantum states shared by the two parties. The CHSH
