Research paperComputational MultiscaleTheoreticalOptimizing Quantum Photonic Integrated Circuits using Differentiable Tensor NetworksMathias Van Regemortel, Thomas Van VaerenbergharXiv·2026·10.48550/arxiv.2509.11861·arXiv:2509.11861AbstractWe present a gradient-based optimization method for quantum photonic integrated circuits, composed of nonlinear unitary coupling gates and stochastic nonunitary components for sampling photonic losses. Differentiable tensor networks are used to simulate low-photon-occupation quantum circuits and to optimize designs for quantum state preparation and quantum phase-sensing readout, with field simulations of GaAs-based samples used to characterize the gate architecture.Read more
