Report summary

For Paderborn University Institute for Photonic Quantum Systems Phoqs in 2015-2026, the graph shows 13 visible PIs and 23 internal PI collaborations. The dominant subject mix is Physics and Astronomy as the leading field (42% of slots across 13 PIs; 13 labels), Atomic and Molecular Physics, and Optics as the leading subfield (34% of slots across 12 PIs; 12 labels), and Quantum Information and Cryptography as the leading topic (13% of slots across 5 PIs; 5 labels). The network looks reasonably well-rounded, with visible collaboration groups but not so much concentration that one field explains the whole department. The top weighted PIs are Christine Silberhorn (58.5 weighted works; Quantum Information and Cryptography, Photonic and Optical Devices). The most visible ties are Christof Eigner and Christine Silberhorn (71 shared works, weight 27.8); Christine Silberhorn and Tim J. Bartley (45 shared works, weight 22.5). The standout breakdown groups are group 1 with 10 PIs, 20 internal connections, weight 96.5, around Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, Artificial Intelligence, led by Christine Silberhorn, Thomas Zentgraf, Tim J. Bartley.
