FormFactor, Inc. (NASDAQ: $FORM (-0,23 %)) is actively involved in the quantum computing industry, offering a range of cryogenic test and measurement solutions for quantum engineers.

A legit pick and shovel player that provides cryogenics to the biggest QC players in the market like Google, IBM, Intel, and Microsoft. Their product was highlighted in Google Willow’s announcement which went unnoticed. Their involvement in QC isn’t really priced in to their current semiconductor biz. Additionally, over 96% of their stock is held by institutions.

This quote from FormFactor's investor relations is compelling:

"99.9% of the quantum computing operations in the United States are using us, big players IBM, Google, Microsoft, Intel... We are the only North American supplier."
