Helium-3 Supply for the Quantum-Computing Industry

Helium-3 cools quantum computers to near absolute zero; a fusion isotope platform is a route to a supply that is otherwise very scarce.

Why quantum computers need He-3

Many quantum processors must operate at temperatures a few thousandths of a degree above absolute zero. Dilution refrigerators reach those temperatures using a mixture of helium-3 and helium-4. Helium-3 is rare on Earth, and demand from quantum computing, cryogenics, and neutron detection strains the available supply.

The supply problem

Kronos motion — quantum supply

Existing helium-3 comes largely from tritium decay in aging stockpiles, a source that does not scale with demand. A fusion isotope platform offers a physics-based route to helium-3, because tritium decays into it and fusion processes involve it directly.

Where computing enters

The burner connection

The Aegis and MetroVolt burner runs on D-3He, so helium-3 is central to Kronos physics on both the supply and the fuel side. The relationship between producing He-3 and consuming it is modeled explicitly rather than assumed away.

Honest framing

Kronos treats helium-3 as strategically important rather than as a headline quantity. The value is in providing a scalable supply mechanism for a critical enabling material, and the yield mechanisms remain open technical questions carried with their uncertainty.

Downstream

A reliable He-3 supply supports the broader push toward quantum-enabled chemistry and materials, a long-horizon application that in turn could improve fusion modeling.
