Mid-circuit logic executed in the qubit layer of a quantum processor

The first mid-circuit measurements performed directly in a silicon spin qubit system, with feedforward decisions made in the quantum layer itself rather than being routed through classical electronics. This 'in-layer' approach matches the classical alternative on key performance benchmarks, pointing to a way of easing the data-handling burden and power demands of future large-scale quantum computers.

Industry-compatible silicon spin-qubit unit cells exceeding 99% fidelity

A landmark demonstration that silicon spin qubits built with standard semiconductor foundry tooling can achieve two-qubit gate fidelities above 99%, a threshold previously reached only with custom fabrication. The result shows that high-performing qubits can be reliably fabricated using existing 300-mm industrial processes, paving the way for mass-manufacture of Diraq’s quantum computers.

Spin-qubit control with a milli-kelvin CMOS chip

Diraq’s collaboration with Emergence Quantum reveals that our silicon spin qubits can be controlled by a custom CMOS chip operating at the same ultracold temperatures as the qubits themselves, deftly addressing the wiring bottleneck that comes with scaling to millions of qubits. The integrated chip performs qubit logic operations with little impact on single- and two-qubit gate performance.
