Problems being addressed.

  * Minimize learning by osmosis.  Implement more direct instruction in a more scaffolded manner.
  * Reduce subjective grading.  Replace with more small assignments that can be assessed more directly.

====== Single Photon Interference ======

----

In this lab you will investigate the quantum mechanical properties of individual photons of light.  

You will learn about and gain experience working with apparatus and techniques that are used extensively in fields such as quantum information, and atomic physics.

====== Part 1 ======

===== Random Event Counting =====

Review of statistics relevant for random counting experiments followed by some quick exercises using pulse counting and coincidence detection electronics.




====== Prelab ======

To be eligible to work on this experiment students must have taken quantum up to at least PHYS235.  They will need to be familiar with the following concepts before coming to the first day of lab:

  * The properties of photons.
  * Spontaneous Parametric Down Conversion.
  * Single Photon Interference.
  * How linear polarizers, half waveplates and quarter waveplates work.
  * Quantum which way information.
  * Wave Particle Duality.
