Diraq demonstrates high-fidelity quantum chips with 99.9% accuracy

Product updates

  • Sydney-based quantum computing company  Diraq has achieved a record control accuracy of 99.9% in a quantum processor using industry-standard silicon wafers. The device comprises a silicon spin qubit made in a 300 mm foundry environment using standard CMOS materials and processes.

  • The device allows for sophisticated qubit control and measurement techniques, including real-time feedback, optimized qubit initialization, control voltage pulse shaping, and advanced analysis tools such as gate set tomography (GST) and randomized benchmarking.

  • Diraq claims that the high fidelity of the qubit device paves the way for integrating high-quality qubits with standard CMOS transistors on a single chip, which is crucial for developing commercially viable, error-corrected quantum computers with millions of qubits. The company intends to leverage existing semiconductor foundry capabilities to develop quantum processor chips on a large scale. In connection with this, GlobalFoundries will manufacture a sample batch of Diraq’s chips later this year.
