Quantum Optics Experiments with Single Photons
July 28, 2026 to July 30, 2026
Number of setups available: 2
Maximum number of participants: 6
------------------------------------------------------------------------------------------------------------------------------------------
The
goal of the Immersion is to show the participant how to setup, successfully
implement, and understand the underlying physics, of quantum optics
experiments designed to illustrate the fundamentals of quantum physics. The
experiments will include:
a) Generation and detection of photon pairs via spontaneous parametric down conversion.
b) Three quantum optics experiments: single-photon interference, the quantum eraser and polarization entanglement (including the Bell test). Will include the use of motorized components for remote operation.
c) Experience with advanced demonstration setups on:
a. Hong-Ou-Mandel Interference (prealigned).
a. Double-slit interference with single photons (Demo)
d) The objective is to learn how to set up the experiments and learn how to do the alignments. It also includes discussions of the equipment to acquire and options available.
e) Immersion Outline: Five half-day sessions of presentation and discussion followed by hands-on sessions in the lab (we start with a clean breadboard and end taking data on each of the experiments).
f) No prior experience is necessary. Bring ideas of what you expect to accomplish back home and what you want to learn.If you already have equipment that you find is not working, you can bring it and we can test it here.
A cost estimate for implementing the experiments. A basic setup is likely to be about $10k. Additions to this setup for various experiments runs about $2k-$10k, depending on the experiment.
Host and Mentor:
Enrique “Kiko” Galvez got a B.S. in physics at the
Pontifical Catholic University of Peru and a Ph.D. in physics from the
University of Notre Dame. He has been at Colgate University since 1988 where he
is the Charles A. Dana Professor of Physics and Astronomy. His research
interests include geometric phases in optics, studies of complex light and
photon entanglement. Since 1999 he has developed new quantum optics laboratories
to teach quantum physics. He has received the APS Award for Research at an
Undergraduate Institution and the Jonathan Reichert and Barbara Wolff-Reichert
Award for Advanced Laboratory Instruction. He is also a Fellow of OSA, APS, and SPIE.
Please note that the Jonathan F. Reichert Foundation has established a grant program
to help purchase apparatus used in Laboratory Immersions. Limitations
and exclusions apply, but generally speaking the Foundation may support
up to 50% of the cost of the required equipment.
