Bell diagonal states refer to a specific class of quantum states that are represented as mixtures of Bell states, which are the four maximally entangled states of two qubits. The Bell states are defined as follows: 1. \\( |\\Phi^+\\rangle = \\frac\{1\}\{\\sqrt\{2\}\} (|00\\rangle + |11\\rangle) \\) 2.
