My group and I will be at CLEO 2025 with several contributions in classical and quantum photonics. For more details, please visit the CLEO website See you in Los Angeles!

Happy to share the results of our collaboration on frequency-bin entanglement-based QKD, published in NPJ Quantum Information. Using silicon ring resonators and real-time phase correction, we achieved secure key distribution over 26 km of fiber at 4.5 bps.

Our new Phys. Rev. A work introduces a compressed-sensing-inspired method that drastically reduces measurements needed for quantum state tomography of N-qudit systems.

Our new work on selective Q-factor tuning in silicon nitride microresonators has been accepted in J. Lightwave Technol.—from 65k to 3M, without disturbing other modes! Stay tuned!

Exciting news! Our paper “Versatile chip-scale platform for high-rate entanglement generation using an AlGaAs microresonator array”, a collaboration between UniPV and UCSB has been accepted in PRX Quantum! Stay tuned for publication updates.

We demonstrate how III-V semiconductor microring resonators can efficiently generate photon pairs and squeezed vacuum states via angular spontaneous parametric down-conversion. Read more.

Join us for the 2nd Congress of the National Quantum Science and Technology Institute (NQSTI), bringing together leading researchers and innovators in quantum technologies. Don’t miss this key event! Learn more.

We’re thrilled to announce the publication of our article, "Photonic multipartite entanglement in discrete variables without arbitrary unitaries," Check new approaches to achieve entanglement in Physical Review Research! 

Wishing everyone a joyful and prosperous 2025! May the new year bring exciting opportunities, success, and happiness. Happy New Year!

Jacopo Piantanida Chiesa, PhD candidate at Leiden University talks about the present and the future of superconducting nanowire single-photon detectors on December 18th at 3 PM in Aula dottorato.

Looking forward to a week at Xanadu Quantum Technology in Toronto, Canada, from Nov 23 to Nov 30. I’m excited to share insights on quantum photonics advancements and explore cutting-edge research with the Xanadu team.

Check out our new Optics Letters publication, “Squeezing enhancement by suppression of noise through a resonant interferometric coupler” in which we show a new integrated device to improve squeezing in realistic condition. Don’t miss it!
