Exchange Symmetry in Multiphoton Quantum Interference
Shreya Kumar, Alex E Jones, Daniel Bhatti +1
Photons are bosons, and yet, when prepared in specific entangled states, they can exhibit non-bosonic behaviour. While this phenomenon has so far been studied in two-photon systems…
Ultracompact Low-Loss Grating Couplers
Shiang-Yu Huang, Jonas Zatsch, Tim Engling +2
Fiber-to-chip couplers play a crucial role in interfacing on-chip photonic circuits with other optical systems or off-chip devices. Downsizing the couplers via topology optimizatio…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Klaus Blaum, Peter Kaufmann, Jochen Kronjäger +168
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
Multiphoton Quantum Interference at Ultracompact Inverse-Designed Multiport Beam Splitter
Shiang-Yu Huang, Shreya Kumar, Jeldrik Huster +3
Photonic quantum technologies enter a new phase when realized in photonic integrated circuits, leading to a great advance in practical applications. In the pursuit of high integrat…
