When investors think “quantum,” they usually picture futuristic computers from companies like IonQ, D-Wave, or IBM Quantum. But behind every quantum breakthrough is a quiet army of infrastructure players — the companies making the lasers, cryogenic systems, measurement tools, and testing gear that make the quantum dream possible.
These stocks may not get the flashy headlines, but they’re the picks-and-shovels of the quantum gold rush. And just like in history, the ones selling the tools often do just as well — or better — than the miners themselves.
1. FormFactor, Inc. (NASDAQ: FORM)
FormFactor is a leader in semiconductor testing, but its real quantum relevance comes from its cryogenic probe stations. Quantum chips — especially superconducting qubits — operate near absolute zero. FormFactor’s systems let engineers test and validate these delicate devices in the same frigid environments they’ll run in.
2. Keysight Technologies (NYSE: KEYS)
Keysight builds quantum control and measurement electronics, providing the precision needed to manipulate qubits without destabilizing them. They’re already working with leading quantum labs and tech firms to fine-tune the “nervous system” of future quantum machines.
3. Oxford Instruments plc (LSE: OXIG)
From ultra-low-temperature refrigerators to nanofabrication systems, Oxford Instruments is at the heart of quantum hardware R&D. Their dilution refrigerators are practically a requirement for superconducting qubit experiments.
4. Bruker Corporation (NASDAQ: BRKR)
Bruker’s high-resolution scientific instruments, especially for material characterization, are critical in developing quantum-grade superconductors, diamond-based NV centers, and photonic materials.
5. Ametek, Inc. (NYSE: AME)
Ametek may be a diversified industrial name, but its precision measurement tools and niche electronic components are deployed in quantum optics and low-temperature environments, making them an indirect — but important — player.
Why These Matter
Quantum computing isn’t just about algorithms and code. Without the ability to build, test, and measure at quantum scales, the industry would stall. These companies are the invisible hands shaping the next big leap in computing.
By focusing on infrastructure players, investors can gain exposure to the quantum revolution without betting on which qubit technology wins — superconducting, trapped ion, photonic, or otherwise.
Bottom Line: If you want a safer but still cutting-edge way to invest in quantum, consider the companies providing the picks and shovels. They may never put “Quantum” in their name, but they’re the ones making it all possible.
