Quantum teleportation leverages the unique principles of quantum mechanics to achieve state transmission and information processing. The system generates polarization-entangled photon pairs through spontaneous parametric down-conversion (SPDC) in nonlinear crystals. Wave plates prepare an initial state on one photon carrying polarization information, after which a Bell-state measurement is performed; meanwhile, the other photon of the entangled pair reconstructs the target quantum state. Offering high information capacity and high reliability, this method realizes quantum state transmission achievable by neither purely classical nor purely unentangled quantum techniques. As a pivotal technology in quantum computing and quantum communication, this system features strong hands-on operation and helps users gain a deep understanding of the fundamental properties of quantum mechanics.
