The top diagram shows a collection of particles on the left side of a divider. If you imagine removing the divider the motion in aggregate is going to be described by a decaying exponential with a real term in the exponent. The lower diagram shows the same setup with only Read more…
David Tong: Lectures on Quantum Field Theory Video Lectures on Quantum Field Theory These are videos of the lectures given at the Perimeter Institute PSI programme in 2009. Each video is in wmv format and somewhere around 130 Mb. More formats are available for download at the Perimeter Institute webpage Read more…
The terminology makes it appear as if he is talking about a FET with source, drain and gate. A lecture explaining Double Quantum Dots during the 2011 Undergraduate School on Experimental Quantum Information Processing (USEQIP) at the Institute for Quantum Computing.

Polarizer material experiment @ see 15:00 to 16:00 into the video below —– 0 deg | —- 90 deg | = nothing comes out. —– 45 deg | —– 0 deg | —– 90 deg | = ~nothing comes out. I am calling the leakage "0" —– 0 deg | —– Read more…
Simplification using single particle experiment explanations Consider a single particle source. The particle is equally likely to emit in any direction. That situation is depicted below : What you imagine is that a localized particle emanates from the emitter and you detect it somewhere on your ring of Read more…
Louis DeBroglie does not get the credit he deserves for original thinking in quantum machanics – DeBroglie thesis paper – he won the Nobel Prize in 1929 for very good reasons which you will see if you read his thesis paper. I am looking for the single photon counter used Read more…
Comments This video is not the most entertaining as the speaker has a thick Germanic accent. However the topic of generating a single photon is important for being able to do experimental quantum physics. Summary In recent years there has been increasing interest in systems capable to generate photon fields Read more…
A reasonable strategy for learning QED would be to try to recreate Richard Feynman's path of discovery that lead him to his thesis paper. If you are an electrical or computer engineer you should probably set about the task of learning the subject for sooner or later quantum computing and Read more…
