Tailored quantum interactions: a recipe from optics

Excellent articulation between falsifiable predictions, quantitative bounds and the testing protocol: each prediction is associated with a measurement method, an expected effect size and a clear null hypothesis, a combination that is both rare and commendable.

The hypothesis proposes an elegant and potentially powerful conceptual transfer between two mature domains (non-linear QPM optics and quantum Hamiltonian engineering), drawing on the formal analogy of optimisation in Fourier space. This 'inverse-design' approach is promising for the generation of programmable non-local interactions, a central challenge for quantum simulation.

The analogy with quasi-phase-matching (QPM) in nonlinear optics is intellectually stimulating and proposes an elegant mathematical framework for the design of synthetic Hamiltonians.

Captive market identified: manufacturers of quantum simulators (IonQ, QuEra, IBM Quantum, Pasqal) and R&D laboratories in materials science (BASF, Dow, Mitsubishi Chemical) that seek to model long-range Hamiltonians for high-temperature superconductivity or topological insulators, without having to rewire their hardware.

High conceptual originality: transfer of quasi-phase-matching (non-linear optics) to the design of synthetic Hamiltonians in programmed quantum matter. An inverse-design approach little explored in this context, offering a strong competitive advantage for ERC or ANR JCJC funding.
