Quantum Particle Entanglement
Quantum particle entanglement, a phenomenon in quantum mechanics, plays a pivotal role in the foundation of quantum key distribution for the Quantum One-Time Pad. In the domain of quantum entanglement, the behavior of two or more particles becomes interconnected in such a way that the state of one particle instantaneously influences the state of its entangled partner, regardless of the distance between them.
When it comes to quantum key distribution for the Quantum One-Time Pad, photon pairs are commonly used for entanglement. These photon pairs are generated in a way that their quantum states are correlated, leading to entanglement. The table below provides a simplified illustration of this concept:
