Studies how multiplexed gradient descent scales with network size. In the tasks studied, time to reach a target accuracy need not increase linearly with parameter count and can decrease for larger networks.

Pushes single-photon detectors to strips 0.1 mm wide — a thousand times wider than conventional nanowires — while keeping intrinsic detection efficiency, reshaping what geometries large-area detectors can use.
