Experiment Learn How Information Can Be Encrypted and Sent Using the Polarization of Light Generate an Encryption Key that Allows for Private Communication Encrypt, Transmit, and Decrypt a Secret Message Examine How an Eavesdropper Causes Errors in Transmission that Can Be Detected Demonstrate the Steps of the BB84 Encryption Protocol The EDU-QCRY1(/M) Quantum Cryptography Analogy 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. The kit includes the lasers, half-wave plates, polarizing beamsplitters, and detectors required to model the sender (Alice), the receiver (Bob) and the eavesdropper (Eve).

Click to Enlarge Binary information encoded in the polarization state of light is detected by a sensor module (indicated by a blue LED).

Thorlabs Educational Products Thorlabs' line of educational products aims to promote physics, optics, and photonics by covering many classic experiments, as well as emerging fields of research. Each kit includes all the necessary components and a manual that contains both detailed setup instructions and extensive teaching materials. These kits are being offered at the price of the included components, with the educational materials offered for free. Technical support from our educational team is available both before and after purchase. Purchasing Note: English and German language manuals/teaching information are available for this product. The imperial kit contains the English manual and US-style power cords. The appropriate manual and power cords will be included in the metric kit based on your shipping location. Please contact Tech Support if you need a different language, cord style, or power supply. As with all products on our website, taxes are not included in the price shown below.

Based on your currency / country selection, your order will ship from Newton, New Jersey
