High-purity frequency-degenerate photon pair generation via cascaded SFG/SPDC in thin film lithium niobate
Olivia Hefti, Marco Clementi, Enrico Melani +12
Frequency-degenerate photon pairs generated using nonlinear photonic integrated devices are a crucial resource for scalable quantum information processing and metrology. However, t…
Time-resolved certification of frequency-bin entanglement over multi-mode channels
Stéphane Vinet, Marco Clementi, Marcello Bacchi +7
Frequency-bin entangled photons can be efficiently produced on-chip which offers a scalable, robust and low-footprint platform for quantum communication, particularly well-suited f…
Generation of hyperentangled photon pairs in the time and frequency domain on a silicon photonic chip
Sara Congia, Massimo Borghi, Emanuele Brusaschi +10
Multi-dimensional entangled photon states represent an important resource in quantum communication networks. Specifically, hyperentangled states presenting simultaneous entanglemen…
Post-selection free time-bin entanglement on a thin-film lithium niobate photonic chip
Marcello Bacchi, Andrea Bernardi, Marco Clementi +8
Time-bin entanglement is the most commonly used form of entanglement for quantum communication protocols over fiber networks, due to the natural resilience of this encoding scheme…
Quantum interference with time-frequency modes and multiple-photons generated by a silicon nitride microresonator
Massimo Borghi, Emanuele Brusaschi, Marco Liscidini +2
We demonstrate bipartite gaussian boson sampling with squeezed light in 6 mixed time-frequency modes. Non-degenerate two-mode squeezing is generated in two time-bins from a silicon…
Frequency-bin entanglement-based quantum key distribution
Noemi Tagliavacche, Massimo Borghi, Giulia Guarda +5
Entanglement is an essential ingredient in many quantum communication protocols. In particular, entanglement can be exploited in quantum key distribution (QKD) to generate two corr…
