HRL Laboratories Demonstrates Self-Running Silicon QPU in Nature Benchmark

HRL Laboratories has demonstrated an 18-qubit silicon spin quantum processing unit (QPU) that operates autonomously by integrating a custom cryogenic CMOS control chip inside the same cryostat. Published in Nature, the breakthrough addresses a critical scaling bottleneck by eliminating the need for racks of external room-temperature electronics, establishing a manufacturing blueprint for scalable quantum processors using standard semiconductor production lines.
