Photodigm
Photodigm manufactures compact laser diodes used as stable optical sources in quantum apparatus. Its quantum-computing relevance is directly evidenced by a laser’s role in controlling an atom–cavity experiment.

What it does. Where it fits.
Monolithic single-frequency semiconductor distributed-Bragg-reflector laser diodes in configurable packages.
Who should look closer
Atomic and quantum-optical engineering teams requiring compact single-frequency laser components.

The catalog offers wavelength and packaging choices; specific availability and custom frequency selection are handled by enquiry.
Check the current access route ↗What has been demonstrated
The Harvard/MIT methods identify the laser and locking chain and report tuning across the rubidium hyperfine range.
What remains unresolved
The cited laser is one component of a larger research apparatus. Qubit and entanglement results are not supplier-only performance, and current availability of that exact historical model is not established.
The next question to watch
Extend independent operating and lifetime data across current laser models in quantum processors.
A research question, not a promised milestone.QubitWire coverage
