My Goodreads Rating: 3 of 5 stars
Trying to teach undergrads general relativity is about as easy as teaching a puppy… general relativity. Hartle strikes a pretty good balance with this book, offering 30-page chapters with *gasp* only a half-dozen equations that focus on conveying high-level concepts as well as chapters fully devoted to tensors, [...]

Progress Report: Beautifying Equations
May 1st, 2010 3 Comments
Before Professor Lidar and I dive into optimization, I’m trying to reproduce the results found in Table 1 of the Invisible Quantum Tripwire paper, specifying the efficiency of the IFM procedure for various settings of the parameters (number of times the photon cycles through the interferometer, total phase rotation angle, and amount of loss in [...]

Progress Report: IQC Project Defined
April 30th, 2010 3 Comments
This morning I had a call with IQC’s Andrew Childs and we pinned down our summer project. The goal is to investigate the analog of “Levinson’s theorem” (originally formulated for general scattering problems) for the case of scattering on graphs. Levinson’s theorem basically relates the phase shift of a scattered state to the [...]
