Dual wavelength source of entanglement for space quantum communication
Valentin Dumas, Alek Lagarrigue, Tess Troisi +4
We report the demonstration of a bulk, intrinsically phase-stable source of polarization- and time-energy-entangled photon pairs at 810nm and 1550nm, directly coupled into single-m…

Highly Nondegenerate Entangled Photon Source for Fiber-Based Quantum Key Distribution
Vasile-Laurentiu Dosan, Alek Lagarrigue, Alessandro Zannotti +4
Entangled photon sources (EPSs) are essential building blocks for scalable quantum communication and quantum key distribution (QKD). We present a stable, highly nondegenerate EPS b…

Mid-infrared quantum scanning microscopy via visible light beyond spatial correlations
Josué R. León-Torres, Vasile-Laurentiu Dosan, Marija M. ÄurÄiÄ +4
The mid-infrared (MIR) region of the electromagnetic spectrum spans from 2- to 25-, serving as a valuable tool for accessing rich chemical information. Functional gro…
