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 [...]

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 bound states [...]

A few weeks ago, I began a project with USC Professor Daniel Lidar to improve the efficiency of a nifty little procedure called “interaction-free measurement.” Here’s the picture: A terrorist tells you he has planted a super-sensitive bomb in one hallway of a building, but you don’t know which one. The bomb will detonate if [...]
