DESCRIPTION:Avenues for using reference frame independent protocols to enhance free space satellite quantum communications channels\n\nAbstract\n\nFree-space quantum channels for real world quantum information applications are rapidly emerging\, with Canada developing the quantum encryption and science satellite (QEYSSat). For polarization-based systems\, one challenge is aligning the reference frame of the polarization states. For example\, the physical orientation of the satellites is crucial in maintaining the proper geometric reference frame alignment. However\, reference frame independent (RFI) protocols overcome this issue because they don’t require all the polarization states to be fixed. Furthermore\, using time bin encoding completely removes the need for a geometric reference\, but presents its own challenges when used over a free space channel. In this talk\, we will discuss the development done at the University of Waterloo towards the use of reference frame independent protocols for free-space quantum channels. Furthermore\, we will discuss the benefits of using time bin encoding over free-space channels\, and present our implementations of such systems and what they mean for future QEYSSat missions and applications on other platforms.
