Presentation Title:
Free-space qubit transport through a lab-scale turbulence testbed
Presentation Abstract:
We developed a laboratory-scale turbulent atmosphere simulator for qubit (TASQ) testbed to parametrically study the role of turbulence on the quantum information content during a free-space qubit transport. We will report the development, characterization, and calibration of the testbed for the statistical parameters of the turbulence employing two phase screens, which produced weak to strong turbulence replicating long distances in the atmosphere for single-photon propagation. We will discuss the parametric effect of turbulence on the quantum statistics of heralded single photon, HOM dip and quantum state tomography employing this testbed. The calibrated setup will provide critical data for field experiments involving long-distance quantum networks.
