What about if you then feed that into a DRBG?

TRNG based on quantum vacuum:

There are NIST randomness tests, for example;

> Here we demonstrate a fully traceable random number generation protocol based on device-independent techniques. Our protocol extracts randomness from unpredictable non-local quantum correlations, and uses distributed intertwined hash chains to cryptographically trace and verify the extraction process. This protocol forms the basis for a public traceable and certifiable quantum randomness beacon that we have launched.

FWIU also there are already QRNG or QTRNG based upon photonic speckle pattern interference; LEDs and a photodiode and an FPGA or an RP2040 or better.
