The Quantum Computer That Works at Room Temperature | Infleqtion CEO Matthew Kinsella

The UK just put quantum clocks on military submarines. Here's why that matters, and what it tells us about the quantum computing race.

Matthew Kinsella, CEO of Infleqtion, explains how neutral atom quantum computers work at room temperature, no supercooling required. Unlike trapped ion or superconducting systems, neutral atoms offer something unique: the same technology powers quantum computers, atomic clocks, and sensors.

This isn't just faster computing. It's GPS-independent navigation, unhackable timing, and scalability that other quantum approaches can't match.

We explore:

- Why submarines need atomic precision underwater

- How quantum clocks provide GPS-independent timing

- The difference between physical and logical qubits

- Neutral atoms vs other quantum modalities (superconducting, trapped ion, spin qubits)

- When quantum advantage becomes commercially useful (Matthew says: 100 logical qubits)

- Infleqtion's platform strategy: clocks, sensors, and computers from the same tech

- Why NVIDIA is partnering with quantum companies for hybrid workflows

Matthew breaks down how lasers manipulate rubidium atoms into the coldest places in the known universe, the Rydberg state that enables entanglement, and why this approach is winning the scalability race.

If you've been waiting for quantum computing to become practical, this is the episode that shows you it's already happening.
