Basic QRNG Electrical Schematic

I’m building a Quantum Random Number Generator (QRNG) that will sit inside an industrial setup and need a clear, entry-level electrical schematic to guide the next steps. The goal for now is a straightforward blueprint—nothing exhaustive—showing how the photon source, detector, amplification stage, entropy extraction logic and power rails tie together.

Scope
• Produce a single-page electrical schematic in KiCad, Altium, Eagle or any mainstream CAD tool.
• Include reference designators, signal names and basic values so I can price components.
• Deliver the native design file plus a PDF export.

Nice-to-haves (keep simple)
• A short BOM listing readily available parts.
• Notes on critical tolerances or shielding considerations for an industrial floor.

I don’t need board layout, 3D renders or compliance paperwork yet—just the initial schematic I can review and iterate on later. If you’ve drafted schematics for photonics or random-number hardware before, that experience will help, but anyone comfortable with precision analog front-ends is welcome.

Please let me know which CAD tool you’ll use and roughly how soon you can turn around this draft.
