Once you have gone through the lower level blocks that make up the balanced amplifier the next step is to simulate the whole balanced amplifier subsystem.

2 Slit with Measurement at One Slit – A quantum view of re-emission

2-Slit_ReEmit

Sequence of Events

  • 50% of the time a photon will be detected at the output of the left hand slit
  • Source emits single photon
  • Photon travels through both slits
  • Due to the right hand path being low probability amplitude the interference pattern at the left slit is not complete interference.  It is lump with squiggle superimposed on it.
  • The photon is measured there.  
  • Since the photon is measured at the output of the left slit due to energy conservation it precludes it also being at the output of the right slit.  Thus it must be considered as mostly re emitted from the measurement location.
  • The photon travels on to the screen where you see very little interference in the pattern.

So maybe the photon always goes through both slits at least somewhat?

Book: Advanced Quantum Mechanics – Freeman Dyson

He did not just invent the vacuum cleaner

When Richard Feynman left Cornell Freeman Dyson was asked to fill in for him and teach an advanced quantum mechanics class.  His notes from that class have been made into a book and are available in pdf form.

The story behind the book is told in the video below.  David Bohm taught Freeman Dyson QM.
