Realistic quantum network simulation for experimental BBM92 key distribution
Michelle Chalupnik, Brian Doolittle, Suparna Seshadri +8
Quantum key distribution (QKD) can provide secure key material between two parties without relying on assumptions about the computational power of an eavesdropper. QKD is performed…
On-chip frequency-bin quantum photonics
Karthik V. Myilswamy, Lucas M. Cohen, Suparna Seshadri +2
Frequency-bin encoding furnishes a compelling pathway for quantum information processing systems compatible with established lightwave infrastructures based on fiber-optic transmis…
Quantum nonlocal modulation cancellation with distributed clocks
Stephen D. Chapman, Suparna Seshadri, Joseph M. Lukens +4
We demonstrate nonlocal modulation of entangled photons with truly distributed RF clocks. Leveraging a custom radio-over-fiber (RFoF) system characterized via classical spectral in…
Ultrafast dynamic beam steering with optical frequency comb arrays
Suparna Seshadri, Jie Wang, Andrew M. Weiner
Efficient spatiotemporal control of optical beams is of paramount importance in diverse technological domains. Conventional systems focusing on quasi-static beam control demand pre…
