Researchers at Intel and quantum computing research center QuTech, announced that they have successfully created the first silicon qubits at scale at Intel’s D1 manufacturing factory in Hillsboro, Oregon.
According to Intel, this research is a crucial step towards scaling quantum chips, demonstrating that it is possible for qubits to eventually be produced alongside conventional chips in the same industrial manufacturing facilities.
The result of this latest research is a process that can fabricate more than 10,000 arrays with several silicon-spin qubits on a single wafer having over 95% yield. According to these researchers, their achievement is dramatically higher in both qubit count and yield than the typical university and laboratory processes used today.
Published in the Nature Electronics journal, this research is Intel’s first peer-reviewed research demonstrating the successful fabrication of qubits on 300mm silicon. The research outcomes further highlight the potential for cryogenic controls of a future quantum system and silicon spin qubits, which closely resemble a single electron transistor, to come together in an integrated package.
“Quantum computing has the potential to deliver exponential performance for certain applications in the high-performance compute space. Our research proves that a full-scale quantum computer is not only achievable but also could be produced in a present-day chip factory. We look forward to continuing to work with QuTech to apply our expertise in silicon fabrication to unlock the full potential of quantum,” said James Clarke, director of Quantum Hardware at Intel.
“This research represents a meaningful advancement in our research into silicon spin qubits, which we believe are promising candidates for powering commercial-scale quantum systems, given their resemblance to transistors that Intel has been manufacturing for more than 50 years. Our demonstration of hot qubits that can operate at higher temperatures while maintaining high fidelity paves the way to allow a variety of local qubit control options without impacting qubit performance.”
QuTech is an advanced quantum computing research center consisting of the Delft University of Technology (TU Delft) and the Netherlands Organization for Applied Scientific Research (TNO).
In another event, Intel and Maricopa County Community College District (MCCCD) Arizona, recently announced a new artificial intelligence (AI) incubator lab for students in the state.
