All-optical turbulence mitigation for free-space quantum key distribution using stimulated parametric down-conversion
Aaron A. Aguilar-Cardoso, Cheng Li, Tobey J. B. Luck +4
In this work, we propose and demonstrate a turbulence-resilient scheme for free-space quantum communication. By leveraging the phase conjugation property of stimulated parametric d…

Tailoring Spatial Modes Produced by Stimulated Parametric Downconversion
A. A. Aguilar-Cardoso, C. Li, T. J. B. Luck +4
We theoretically study and experimentally demonstrate controlled generation of spatial modes of light via stimulated parametric downconversion (StimPDC) by transferring the spatial…

Violation of local realism with spatially multimode parametric down-conversion pumped by spatially incoherent light
Cheng Li, Jeremy Upham, Boris Braverman +1
We experimentally demonstrate a violation of local realism with highly spatially multimode polarization-entangled two-photon states produced by spontaneous parametric down-conversi…
