Title: Optimizing All-fiber Broadband Nonlocal Dispersion Compensation for Quantum Communication Networks
Date/Time: 24-May, 02:00PM
Venue: Online via Zoom
Abstract: Spontaneous Parametric Down Converted photon pairs possesses a high degree of temporal correlation. While fiber-based quantum communication networks threaten to degrade these correlations via chromatic dispersion, they can simultaneously serve as a solution to its own problem via Nonlocal Dispersion Compensation. This phenomenon can take into effect when the SPDC source is designed to have its paired photons experience opposite chromatic dispersion coefficients when propagated through the telecommunication fiber, enabling their energy anti-correlation property to minimize the variance in the possible delays between them, and thereby reducing or even nullify the effect of chromatic dispersion on the overall timing correlation. At this juncture, this solution has been shown to be effective in nearly eliminating chromatic dispersion completely across the full, broadband, SPDC spectrum when propagated over 40km of telecommunication fiber with a projected loss of no more than 0.8dB. Some strategies were implemented to optimize the efficacy of this solution, which is the topic of discussion.
