Towards an All-Silicon DV-QKD Transmitter Sourced by a Ge-on-Si Light Emitter
Florian Honz, Nemanja Vokić, Philip Walther +2
We investigate the behavior of a Ge-on-Si light source and demonstrate its feasibility for polarization-encoded discrete-variable quantum key distribution following the BB84 protoc…
Alignment-Tolerant Fi-Wi-Fi Free-Space Optical Bridge
Florian Honz, Aina Val Marti, Philip Walther +2
We demonstrate a simplified out-door FSO link with modal split for down-/uplink and confirm its long-term stability without active beam tracking. We further prove the duality of mo…
Photonic source of heralded GHZ states
H. Cao, L. M. Hansen, F. Giorgino +5
Generating large multiphoton entangled states is of main interest due to enabling universal photonic quantum computing and all-optical quantum repeater nodes. These applications ex…
Polarization-Encoded BB84 QKD Transmitter Sourced by a SiGe Light Emitter
Florian Honz, Nemanja Vokic, Philip Walther +2
We demonstrate a polarization-encoded BB84 transmitter sourced by a SiGe light source and show that such a potentially "all-silicon" QKD scheme can operate well below the QBER thre…
Controlling the Photon Number Coherence of Solid-state Quantum Light Sources for Quantum Cryptography
Yusuf Karli, Daniel A. Vajner, Florian Kappe +14
Quantum communication networks rely on quantum cryptographic protocols including quantum key distribution (QKD) using single photons. A critical element regarding the security of Q…
Benchmarking the human brain against computational architectures
Céline van Valkenhoef, Catherine Schuman, Philip Walther
The human brain has inspired novel concepts complementary to classical and quantum computing architectures, such as artificial neural networks and neuromorphic computers, but it is…
