We demonstrated bipartite Gaussian boson sampling with squeezed light in time-frequency domains from a silicon-nitride photnic chip. High-fidelity four-photon events probed isomorphic graph similarity. Full results are avialble in npj Quantum Information.

I will attend the workshop "New Trends in Photonics" in Como, September 16–18 2025, where I will present the contribution "Squeezing nonclassical light out of a photonic chip". Looking forward to inspiring discussions!

Our work on the generation of hyperentangled photon pairs in the time and frequency domain on a silicon photonic chip is now avaialble in Optics Letters.

Our work on ultrabroadband resonant frequency doubling on a chip is now available in Nature Communications! We demonstrate over 200 nm of second-harmonic bandwidth using linearly uncoupled microrings with reconfigurable phase matching.

Our paper on the modeling and optimization of pulsed squeezed state generation in a ring-resonator system” is now published in Physical Review A. 

I will be speaking at ICTON 2025 in Barcelona, July 6–10 2025, on the latest breakthroughs in integrated photonics. Join me for engaging sessions and networking at the International Conference on Transparent Optical Networks! 

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.
