Several courses introducing students to research in applied physics are given by our group, they are all based on one principle: learning by doing. Our quantum entanglement lab gives undergraduate students an opportunity to measure a quantum effect at the heart of current research: polarization entanglement in pairs of photons. The course electronics for physicists provides graduate students with the understanding and knowledge in electronics required to run complex physics experiments. The quantum entanglement course gives advanced undergraduate students an opportunity to delve deeper in quantum science and to get an introduction to research in quantum optics.


Quantum Entanglement Lab Practicum

Entanglement PracticumWe 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.


Electronics for Physicists

Electronics for Physicists

The course is a must-have for PhD students and post-docs interested in experimental physics. We will study electronics with astrong focus on practical applications. After reviewing the basics  of passive and active components and their practical limitations, we will focus on circuit simulation, systematic troubleshooting and opamp circuits. Signals, noise and interference problems (and solutions!) will also be an important topic. We finish with an overview of microwaves and various measurement techniques, and a day on advanced use of electronic measurement equipment. Several case studies from the physics lab will be used throughout the course to make the theory come alive.

Book: The Art of Electronics, Horrowitz and Hill, 2nd edition, Cambridge University Press, New York, 1989. Extra material is handed out during the course. Students should be in possession of the book when the course starts.

Teachers: This is a Casimir course given by Val Zwiller and Raymond Schouten (Delft University of Technology) for TU Delft and Leiden students. The course is mainly intended for Ph.D. students and postdocs (experimentalists as well as theorists) associated to the Casimir Research School, motivated master students are welcome.


Quantum Entanglement

Quantum EntanglementThis is a theory and hands-on course on quantum entanglement: theory will be covered in lectures and students will perform quantum entanglement measurements in the lab. In addition, articles will be discussed. We start with the EPR paper and finish with applications of quantum entanglement.


Topics covered:
– History of quantum entanglement
– Generation schemes of entangled photon pairs
– Experiments and loopholes
– Entanglement in the solid state
– Single photon detection
– Indistinguishable photons
– Entanglement applications: Teleportation, lithography, cryptography, quantum repeaters
