Sample Experiments

Here is a list of the experiments you can do with the quED and its add-ons.

Single Photon Experiments without Interference

• Particle Nature of Photons
• Quantum Cryptography/QKD: BB84 Protocol
• Tomographic Single Photon State Reconstruction
• Quantum Random Number Generation

Single Photon Experiments with Interference

• Double Michelson Interferometer
• Visible (White) Light Interference (Observable by Eye)
• Measurement of the Central Wavelength of Single Photons
• Measurement of Coherence Length of Single Photons
• Interaction-Free Measurement (Bomb Test)

Photon Pair Experiments with Polarisation Entanglement

• Violation of Bell’s Inequality (CHSH)
• “Non-Classical” Polarisation Correlations
• Tomographic State Reconstruction of an Entangled Photon State
• Quantum Cryptography/QKD: BBM Protocol
