Quantum entanglement lab

We maintain and operate an experimental setup used for the measurement of quantum entanglement. This enables undergraduate students to perform quantum entanglement measurements. the setup is based on the downconversion of photons emitted from a small blue laser into pairs of red photons entangled in polarization. The red photons are sent to Alice and Bob for polarization and correlation measurements. Measurements performed with varying polarizer angles can demonstrate a violation of Bell’s inequality.

An introduction and the manual for the lab practicum is available here .
