Room temperature is not a feature. It's the entire product.

Every quantum computer company in the world — Google, IBM, IonQ, Rigetti, PsiQuantum — asks the same question: "How do we get more qubits while maintaining coherence?" And every one of them answers with the same infrastructure: dilution refrigerators, vacuum chambers, cryogenic wiring harnesses, and specialized facilities that cost millions to build and operate.

QLT asks a different question: "What if coherence doesn't require cryogenics?"

The economics of temperature

A dilution refrigerator costs $1–5M. It consumes 25+ kW of power. It takes days to cool down. It requires specialized helium-3, which costs $2,000+ per liter and is subject to supply constraints. A single unit supports one quantum processor. To scale, you need more refrigerators — linearly.

A room-temperature photonic processor requires none of that. It operates on a standard optical bench. It can be rack-mounted. It can be deployed in a SCIF, a submarine, an aircraft, or a data center rack alongside conventional servers. The total cost of the operating environment is effectively zero.

This isn't a minor efficiency gain. It changes the TAM. Cryogenic quantum processors are limited to centralized facilities. Room-temperature processors can be deployed anywhere there is power and a network connection. The market for "quantum computers that need a building" is small. The market for "quantum processors that fit in a rack" is the entire computing industry.

Defense changes everything

The US Department of Defense spends $5B+ annually on quantum technology. But virtually no cryogenic quantum system can be field-deployed. You can't put a dilution refrigerator on a drone. You can't install one in a tactical vehicle. You can't ship one on a submarine without compromising its thermal signature.

QLT's chip operates at 300K. It's ITAR-eligible. It's field-deployable. It can provide real-time quantum-enhanced signal processing, cryptanalysis, and optimization in contested environments where no cryogenic system can operate. Room temperature isn't a feature for DoD. It's the prerequisite.

The market isn't "quantum computing." The market is "computing."

When quantum processing requires cryogenics, it's a niche. When it operates at room temperature, it competes with every processor in every data center, every edge device, every autonomous system, and every handheld communication device on Earth. That's the real product story.

300K is not a spec. It's a market unlock.
