Fabian J. Pauw, Ulrich Schollwöck, Nathan Goldman +2 more·Sep 15, 2025
The interplay between topology and strong interactions gives rise to a variety of exotic quantum phases, including fractional quantum Hall (FQH) states and their lattice analogs - fractional Chern insulators (FCIs). Such topologically ordered states ...
Optimizing Quantum Photonic Integrated Circuits using Differentiable Tensor Networks
Mathias Van Regemortel, Thomas Van Vaerenbergh·Sep 15, 2025
Recent reports of large photonic nonlinearities in integrated photonic devices, using the strong excitonic light-matter coupling in semiconductors, necessitate a tailored design framework for quantum processing in the limit of low photon occupation. ...
