BellZustand
BellZustand, commonly referred to as a Bell state, denotes any of the four maximally entangled two-qubit states that form the Bell basis in quantum information. These states are pure and orthonormal, and they provide a convenient complete basis for the joint state space of two qubits.
Key properties include maximal entanglement, meaning the two qubits cannot be described independently. Each state has
Generation methods vary by platform. In photonic systems, Bell states are commonly produced via spontaneous parametric
Applications of Bell states are central to quantum information science. They enable quantum teleportation, which transmits
