On the Security of Offloading Post-Processing for Quantum Key Distribution
Thomas Loruenser, Stephan Krenn, Christoph Pacher +1
Quantum key distribution (QKD) has been researched for almost four decades and is currently making its way to commercial applications. However, deployment of the technology at scal…
Towards metropolitan free-space quantum networks
Andrej Kržič, Sakshi Sharma, Christopher Spiess +18
Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre based systems h…
Broadband Balanced Homodyne Detector for High-Rate (>10 Gb/s) Vacuum-Noise Quantum Random Number Generation
Florian Honz, Dinka Milovančev, Nemanja Vokić +2
We demonstrate a die-level balanced homodyne detector with a high quantum-to-classical noise clearance of 19.1dB over 3GHz bandwidth. We evaluate this receiver as a high-quality en…
Practical continuous-variable quantum key distribution with composable security
Nitin Jain, Hou-Man Chin, Hossein Mani +10
A quantum key distribution (QKD) system must fulfill the requirement of universal composability to ensure that any cryptographic application (using the QKD system) is also secure.…
Tight Secure Key Rates for CV-QKD with 8PSK Modulation
Florian Kanitschar, Christoph Pacher
We use a recent numerical security proof approach to calculate tight secure key rates in the presence of collective attacks for a continuous-variable (CV) eight-state phase-shift k…
Quantum RNG Integration in an NG-PON2 Transceiver
Nemanja Vokić, Dinka Milovančev, Christoph Pacher +3
We propose a minimally invasive optical overlay for time-interleaved QRNG operation in NG-PON2 transceivers. We experimentally demonstrate that random numbers can be generated at a…
