The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Here, we demonstrate a high-sensitivity MIR upconversion differentiator operating at 3 μm, which achieves isotropic high-order edge enhancement by optically imprinting topological complex-amplitude patterns onto MIR Fourier components via nonlinear parametric interaction.

C2weakest assumption

The phase-only SLM can encode the required vortex transfer functions t(kr, φ) ∝ kr^ℓ e^{iℓφ} with sufficient fidelity that the nonlinear parametric interaction faithfully transfers them to the MIR Fourier plane without introducing significant distortions or losses.

C3one line summary

A nonlinear upconversion system encodes tunable topological vortex patterns to perform first-to-fourth-order isotropic edge differentiation in mid-infrared imaging with single-photon sensitivity.
