| Abstract Title: |
W30: Quantum Cryptography |
| Abstract: |
Our Quantum Cryptography Demonstration Kit contains components to model a data transmission setup using the BB84 encryption protocol. This encryption method allows a sender and receiver to generate an encryption key that only they know and eavesdroppers to be detected. In this analogy experiment, the polarization of transmitted light carries bits of information which are manipulated using half-wave plates and polarizing beamsplitters.
Even though this is a classical experiment because of the use of laser pulses instead of single photons, students are able to experience every step of the BB84 protocol. In particular, they learn about the preparation of a state and how they generate a tap-proof key. The experiment culminates in the placement of Eve between Alice and Bob to demonstrate how her presence inevitably leaves a trace that reveals her presence. |
