During the initial phase of FLATS, the consortium has achieved substantial progress toward establishing twistronics as a foundation for next-generation quantum metrology. A major milestone has been the deployment of the open twistronics platform, which now serves as a shared resource for fabrication protocols, simulation tools, and collaborative development across the consortium. Numerical simulations are converging toward the optimal twist angles for magic-angle bilayer graphene, guiding experimental design and advancing our understanding of correlated flat-band regimes. Experimentally, twisted bilayer graphene has proven to be a versatile platform: we have demonstrated proximity-induced superconductivity across dispersive and flat-band regimes, revealing that superconducting correlations persist even as the bandwidth narrows and that the critical current departs from normal-state scaling in the flat-band limit. These signatures point to interaction-driven contributions to the supercurrent and highlight the increasing influence of quantum geometry and multiband pairing. Building on this foundation, Josephson junctions and single-photon detectors have been successfully realized in MATBG, enabling further exploration of symmetry-broken effects such as the Josephson diode behavior and preparing the ground for future device arrays to be delivered to LNE. Parallel efforts on quantum electronic interferometry have led to significant improvements of the graphite Mach–Zehnder interferometer, which now exhibits tunable coherence well-suited for upcoming QAHE-based experiments. In addition, key metrological protocols—including Hong–Ou–Mandel interference and single-electron tomography—have been demonstrated within the Quantum Hall regime, establishing a solid basis for future operation at zero magnetic field once QAHE is achieved. MATBG-based single-photon detection has reached impressive sensitivities, and development of the THz detection platform continues to progress, despite an anticipated delay of approximately one year for this particularly ambitious milestone. Altogether, the consortium’s accomplishments illustrate rapid scientific momentum and a clear trajectory toward the ambitious goals of FLATS, reinforcing the central role of twistronics in advancing quantum materials and metrological technologies.
