PhD Student in Quantum Optics, working on Quantum Networks at Laboratoire Kastler Brossel (LKB), Sorbonne University.
Master thesis (M2) / Internship: Development, characterization and optimization of single photon pair-sources based on cavity enhanced spontaneous parametric down conversion (SPDC) in bulk non linear crystals to form optical parametric oscillators (OPOs). This work focused particularly on measuring the heralding efficiency of the source. The ultimate objective was to employ these sources to interface atom-based quantum memories with telecom infrastructures contributing to the development of the Quantum Internet.
During my internship at Thales, I focused on the characterization of Indium Gallium Phosphide (InGaP) photonic crystal (PhC) cavities for the efficient generation of entangled photon pairs using spontaneous Four-Wave Mixing (FWM). I developed a novel temperature-based method to tune resonance frequencies through the thermo-refractive effect, which simplifies on-chip integration by eliminating the need for tunable lasers. Additionally, I explored bistable behavior in high-power regimes and successfully measured time-correlated photon pairs, demonstrating the efficiency of the nonlinear processes.
Conducted experimental research on integrating Quantum Key Distribution (QKD) into optical networks, supervised by G. T. Kanellos, with a focus on BB84 and Decoy State BB84 protocols. Demonstrated the integration of an O-band QKD link into a Fiber-to-the-Home (FTTH) GPON network, addressing coexistence with classical channels by mitigating Spontaneous Raman Scattering. Also explored switched-QKD networks, highlighting their scalability and efficiency for large-scale deployment in telecom infrastructures.
