Which Milestones Would Show Progress in VIS-NIR Integrated Photonics?
Part 135 of the Neutral Atom Quantum Computation series, covering 3.2.1 VIS-NIR Integrated photonic platforms and the roadmap's guidance on visible and near-infrared integrated photonics.
⚡ Quantum Brief
The milestone is a packaged photonic subsystem that controls real atoms across required wavelengths with lower size and calibration overhead. The evidence should be repeatable and measured inside a representative system rather than inferred from one favorable component result.
Key takeaways
- Integrated photonics can route, split, modulate, stabilize, and emit the many visible and near-infrared wavelengths needed by neutral atom processors.
- Chip-scale photonics may replace bulky optical benches and make thousands of stable control channels manufacturable.
- Short wavelengths increase scattering and fabrication sensitivity, while no single material offers ideal loss, power handling, and modulation everywhere.
- Co-design silicon nitride, thin-film lithium niobate, alumina, tantalate, and hybrid platforms around atomic transitions.
- Measure propagation loss, coupling efficiency, optical power handling, wavelength coverage, phase noise, footprint, yield, and packaging stability. The milestone is a packaged photonic subsystem that controls real atoms across required wavelengths with lower size and calibration overhead.
