Entangled photon pairs are two photons whose quantum states are linked, regardless of their separation. When two photons are entangled, measuring a property of one instantaneously influences the corresponding property of the other, even across vast distances. This quantum correlation defies classical explanations and forms the basis for quantum communication and computation. Such pairs are produced through processes like spontaneous parametric down-conversion.
Context
Entangled photon pairs are critical components in developing quantum cryptographic systems, specifically for quantum key distribution QKD, which promises theoretically unhackable communication. Scientists are actively working to extend the distance over which entanglement can be maintained and to increase the rate of entangled photon generation. This technology holds significance for future secure digital asset transactions.
Quantum entanglement and the Twine protocol establish a verifiable, fundamentally unpredictable public randomness primitive, fortifying decentralized system security.
