Cryogenics, Photonics and Control Electronics: The Bottlenecks Investors Ignore
Why quantum value may form first in enabling infrastructure, not only in final-system manufacturers.
Quantum is often described through the visible race to build quantum computers, networks and sensors. That framing is incomplete. The deeper industrial question is whether quantum systems can be cooled, controlled, read, packaged, tested, manufactured and certified at scale. Cryogenics, photonics, control and readout electronics, advanced packaging, materials, interconnects, testing and metrology are not secondary technical details. They are the bottlenecks that may determine which companies can industrialise quantum technologies, which suppliers gain pricing power, and which jurisdictions reduce strategic dependence on scarce external capabilities.
