Infineon Technologies AG and Oxford Ionics are working together on high-performance and fully integrated quantum processors (quantum processing units, QPU). The goal is to extract quantum computing from a research lab and transfer it to industrial applications.

Specifically, it is the electronic qubit control (EQC) from Oxford Ionics. This is to be combined with Infineon’s engineering and manufacturing capabilities and the chip manufacturer’s expertise in quantum technology. According to the partners, this forms the basis for industrial production of QPUs with hundreds of qubits over the next five years.

Quantum computing opens up a new dimension of computing power for many industries that want to radically improve their processes and capabilities. This goal requires the development of qubit technologies that can be produced on a large scale.

At the same time, an increasing number of qubits must be controlled and quantum error rates must be kept at or below the current state of the art. Oxford Ionics’ EQC technology offers a way to integrate qubits with an ion trap (leading qubit technology in terms of quantum error rates) with Infineon’s mature semiconductor processes.

scale and efficiency

Chris Ballance, co-founder of Oxford Ionics, explains: “The big challenge in quantum computing is scaling while increasing efficiency. There are technologies that can scale but do not increase performance, and there are technologies that can increase performance but not scale. ” Its own electronic control is configured in such a way that it can guarantee both.

“Working with Infineon and their mature and flexible semiconductor processes allows us to cut the time to commercial QPU,” he continues. Due to previous error rates in in-house technology, these processors “needed drastically fewer qubits to solve significant problems than other technologies.”


Schedules are tight:

  • So he should first devices via Oxford Ionics will be available via the cloud by the end of 2022, giving commercial players access to these technologically advanced quantum computers.
  • Fully integrated versions with enough power to scale to hundreds of qubits should be available in less than two years.
  • Ultimately, Infineon and Oxford Ionics plan to offer single, fully integrated QPUs that will make hundreds of qubits available over the course of five years. They will be networked using Oxford Ionics and quantum network technology A cluster of quantum supercomputers Form.

Stephan Schächer, Infineon Industry Division’s director of new applications, innovation and quantum computing, explains: “Infineon’s role is to scale the pioneering work of Oxford Ionics to obtain the correct qubit count and low error rate. Infineon Ion Traps coupled with our predictable, repeatable and reliable manufacturing and assembly capabilities can make this possible. ”

Infineon Ion Trap Modules

Infineon Ion Traps are accelerating the development of powerful quantum computers for solving optimization problems that cannot be solved with conventional computers. This research began in 2016 at the Infineon facility in Villach to combine scientific knowledge with industrial-scale quantum technologies.

Drawing on its expertise in industrialization and combining cutting-edge materials and technologies, Infineon is paving the way for thousands of qubits by working with partners to integrate control electronics and optics with cryocombination. This should enable scientists and companies to focus on their core tasks, push the boundaries of science and research, and develop successful and convincing quantum computing systems that will enable industry and research to solve important problems.

Next to the ion traps

However, Infineon takes different approaches to quantum computing. In addition to ion traps, the company is also working on superconducting and semiconductor qubits. As co-founder of Quantum Technology and Application Consortium (QUTAC), Infineon supports the topic from technology to feasible application.

In the Quantum Application and Technology Consortium, 10 global corporations from various industries with roots in Germany came together to develop applications for quantum computers.  (Pete Linforth on Pixabay)
