Tim Bode

I lead Quicopt — a quantum-inspired optimization spin-off out of Forschungszentrum Jülich.

Previously: PhD in condensed-matter and many-body theory at the University of Bonn (summa cum laude, 2021). MSc and BSc from ETH Zurich.

pilot projects with industry

Quicopt builds optimization software inspired by quantum physics for problems that classical solvers handle poorly — multi-supplier BOM sourcing, AC optimal power flow, blending and pooling, native higher-order binary optimization. It runs on standard hardware, no QPU required. Hard physics, applied software, shipped.

§ II

Research

My work runs from non-equilibrium field theory through mean-field optimization to beyond-mean-field corrections, with sidelines into field-theoretic methods for stochastic processes (J. Phys. A) and experimental photon condensation (Science) — first-, last-, and sole-author contributions among them.
