HRL Laboratories Demonstrates Self-Running Silicon QPU in Nature Benchmark

In a study published today in Nature, hardware developer HRL Laboratories—jointly owned by Boeing and General Motors—demonstrated an 18-qubit silicon spin quantum processing unit (QPU) that operates autonomously without real-time direction from room-temperature electronics. The integrated architecture replaces traditional racks of external control instruments with a custom cryogenic CMOS control chip operating at 4 K inside the cryostat. The system executed quantum error detection and repetition codes with zero room-temperature latency, addressing a critical scaling bottleneck in physical wiring and thermal management.
