A Bell state is a specific type of quantum state that represents maximal entanglement between two qubits. There are four Bell states, and they form the basis of the two-qubit quantum system. The four Bell states are: 1. \\(|\\Phi^+\\rangle = \\frac\{1\}\{\\sqrt\{2\}\} (|00\\rangle + |11\\rangle)\\) 2.
