Traditional encryption protocols are becoming less secure as quantum computing becomes more viable. Quantum Key Distribution(QKD) uses quantum entanglement to distribute provably secure encryption keys. Previous QKD protocols have used polarization-entangled photons that can be easily measured, but cannot be easily transmitted over long distances. This project will use time-energy entanglement which is more challenging to verify but can be easily transmitted over long distances. This project demonstrates Time-Energy entanglement and proposes a method of verifying security independent of Franson interferometry verification.
