Infineon Technologies AG and Oxford Ionics recently announced a collaboration to build high-performance and fully integrated quantum processing units (QPUs). The combination of Oxford Ionics’ unique electronic qubit control (EQC) technology with Infineon’s world-leading engineering and manufacturing capabilities, as well as expertise in quantum technology, will lay the foundations for the industrial production of QPUs offering hundreds of qubits within the next five years.The goal is to move quantum computing technology out of the research lab into real industrial solutions.

Quantum computing opens up the next frontier in computing power for many industries seeking radical improvement in their processes and capabilities. Getting there requires developing qubit technologies that can be built at a massive scale while controlling a growing number of qubits and maintaining quantum error levels at and below the current state-of-the-art. Oxford Ionics’ EQC technology offers a path to integrating trapped ion qubits – the leading qubit technology by quantum error levels – into Infineon’s mature semiconductor processes.

 “The great challenge in quantum computing is scaling whilst improving performance”, said Chris Ballance, Co-Founder of Oxford Ionics. “There are technologies that can be fabricated at scale but don't perform, and there are technologies that perform but don't scale. Our electronic control is uniquely placed to do both. Working with Infineon and its mature and flexible semiconductor process, allows us to speed up the accessibility of a commercial QPU. Due to our market-leading error rates, these processors need dramatically fewer qubits to solve useful problems than other technologies.”

The first Oxford Ionics devices will be cloud accessible by the end of 2022, offering commercial players access to these cutting-edge Quantum Computers. Fully integrated devices with high enough performance to scale to hundreds of qubits are planned to be available in less than two years. The ultimate goal of Infineon and Oxford Ionics is to offer, within five years, individual, fully integrated QPUs offering hundreds of qubits networked together into a quantum supercomputing cluster using Oxford Ionics’s quantum networking technology.

“The role of Infineon is to take the ground-breaking work of Oxford Ionics to scale properly towards meaningful qubit counts and low error rates. Infineon’s ion traps can enable that in conjunction with our predictable, repeatable, and reliable manufacturing and assembly capabilities,” said Stephan Schaecher, Director of New Application, Innovation, and Quantum Computing at Infineon Technologies Industrial Division.
