Digital reconstruction of squeezed light for quantum information processing
Huy Q. Nguyen, Ivan Derkach, Adnan A. E. Hajomer +5
Squeezed light plays a vital role in quantum information processing. By nature, it is highly sensitive, which presents significant practical challenges, particularly in remote dete…
Experimental composable key distribution using discrete-modulated continuous variable quantum cryptography
Adnan A. E. Hajomer, Florian Kanitschar, Nitin Jain +6
Establishing secure data communication necessitates secure key exchange over a public channel. Quantum key distribution (QKD), which leverages the principles of quantum physics, ca…
Composable Continuous-Variable Multi-User QKD with Discrete Modulation: Theory and Implementation
Florian Kanitschar, Adnan A. E. Hajomer, Michael Hentschel +2
Establishing scalable, secure quantum networks requires advancing beyond conventional point-to-point quantum key distribution (QKD) protocols toward point-to-multipoint QKD protoco…
Continuous-variable quantum passive optical network
Adnan A. E. Hajomer, Ivan Derkach, Radim Filip +3
Building scalable and secure quantum networks with many users has a high application potential but also holds many practical challenges. A significant stride in this pursuit involv…
Future proofing network encryption technology with continuous-variable quantum key distribution
Nitin Jain, Hou-Man Chin, Adnan A. E. Hajomer +6
We demonstrate a proof-of-concept establishment of quantum-secure data transfer links in field trials at two locations in Denmark: on the campus of Technical University of Denmark…
