Overview
Interference is generally considered to be a wave phenomenon. Curiously it also works with single quantum objects. Use the quED and the quED-MI Michelson Interferometer add-on together with the quED to show that this is the case.
There are two versions of the quED-MI, the manual and the motorized version (photo shows the latter).
Sample Experiments
Here is a list of the experiments where the quED-MI is involved.
Single Photon Experiments with Interference
Wave Nature of Photons: Single Photon Michelson Interferometer
Quantum Eraser
Wave-Particle Dualism: Michelson + HBT
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 without Polarisation Entanglement
Franson Interference
These are the experiments we have come up with so far and found interesting enough to put them here. Do you have more ideas? Please let us know!
Other Add-Ons
The functionality of the quED system can easily be extended with these add-ons:
+ quED-HBT Hanbury Brown Twiss Add-On
+ quED-HOM Hong–Ou–Mandel Effect
+ quED-QKD Quantum Cryptography
+ quED-TOM Quantum State Tomography Add-On
System Includes
The quED-MI is an add-on to the quED and consists of the following parts:
- Michelson interferometer with polarization maintaining fibre input and single mode fibre output
- 3 Polarizers that can be swung in and out of the interferometer.
Variants
There are two variants of the quED-MI:
- Manual: Ideal for student lab courses, where the students are supposed to perform the measurements themselves.
- Motorized: Intended for demonstrations during lectures or at science exhibitions, classes and research, when the result matters more than the process of measuring. Here, the linear translation stage is replaced by a motorized one.
