A reconfigurable entanglement distribution network suitable for connecting multiple ground nodes with a satellite

Autor: Vinet, Stéphane, Tannous, Ramy, Jennewein, Thomas

Satellite-based quantum communication channels are important for ultra-long distances. Given the short duration of a satellite pass, it can be challenging to efficiently connect multiple users of a city-wide network while the satellite is passing ove

Towards Fully Passive Time-Bin Quantum Key Distribution over Multi-Mode Channels

Autor: Tannous, Ramy, Wu, Wilson, Vinet, Stéphane, Perumangatt, Chithrabhanu, Sinar, Dogan, Ling, Alexander, Jennewein, Thomas

Phase stabilization of distant quantum time-bin interferometers is a major challenge for quantum communication networks, and is typically achieved by exchanging optical reference signals, which can be particularly challenging over free-space channels

Characterization of optical aberrations with scanning pentaprism for large collimators

Autor: Lee, Youn Seok, Mohammadi, Kimia, Jennewein, Thomas

We present a practical apparatus for characterizing optical aberrations of large collimation mirrors and lenses, and give a detailed analysis of wavefront-detection errors. We utilize a scanning pentaprism technique for precise measurements of local
