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.
