Ireland-based quantum computing company Equal1 has launched a multi-tile quantum controller chip as part of its UnityQ Quantum-System-on-Chip platform. The chip operates at 300 millikelvin temperatures and is powered by British semiconductor company Arm's Cortex core microprocessors.

The quantum controller chip features AI-enabled qubit adaptive error correction tuned for each tile under Arm's Cortex processor control. The chip also demonstrated high-performance metrics on a six-qubit array, achieving 99.4% single-qubit fidelity with 84 nanoseconds gate speed and 98.4% two-qubit fidelity with 72 nanoseconds gate speed.

The company claims the new controller chip will enable scaling to millions of orchestrated qubits on a single chip, facilitate real-time error correction, and provide flexibility to use current and future error correction algorithms. Equal1 also states the technology can be produced using existing silicon infrastructure and conventional foundries.
