Abstract :
This paper presents a slide presentation on entanglement based quantum key distribution (QKD). It first introduced entanglement then discussed the BBM92 protocol for quantum cryptography using entangled states. Then a demonstration of QKD outside the laboratory using entangled photons. A new type of entangled source for long distance QKD is also presented.
