I’m a graduating Physics senior at Southern University and A&M College, in Baton Rouge, Louisiana. Baton Rouge is my hometown, and I have lived there all my life. I have a few research interests in Physics, including condensed matter, quantum information and nanoelectronics. Physics is my favorite thing in the world because at the end of the day, no matter how much I learn, it still feels like magic. The entire universe and everything in it seems like it works by magic to me. Just when we think we’ve got it figured out, something new comes and revolutionizes the way we think.
Constructing a Phase Detector for a Single-Photon Quantum Phase Gate
Our research primarily focuses on creating interactions between photons at the single-photon level. For this purpose, we coherently map the photons onto strongly interacting cold Rydberg atoms using electromagnetically induced transparency (EIT) techniques. In the presence of one or several Rydberg excitations in the medium, the light propagating under Rydberg-EIT conditions will accumulate an extra phase due to the level-shift introduced by the long-range dipole-dipole interaction. This additional phase opens prospects for the construction of a quantum phase gate at the single-photon level. We have devised an interferometer that operates at low-light intensity to detect the imprinted phase on the photons.
