EKPQC Quantum Cryptography Educational Kit

S-Fifteen Instruments EKPQC is a user assembled and operated Educational Kit designed to convey the ideas and steps of a Quantum Key Distribution implementation.  The "quantum channel" is simulated with macroscopic pulses of red laser light and the classical channel with infrared pulses. An optional Eavesdropper Kit is available to exploit the security loophole due to the non-quantum nature of macroscopic laser light.

Note that the kit is designed for educational purposes only, and does not implement Quantum Key Distribution (BB84) secure against side-channel attacks. Classical channel Adruinos not pictured. PCs or Raspberris not included.

Read the Am. J. Phys article the kit is based on.
