While most of the companies pursuing trapped ion quantum processors that use lasers to control the qubits, Oxford Ionics is taking a different approach and using microwaves to control the gate operation. Their thinking it that using microwave control is easier to scale than multiple lasers while retaining the high gate fidelity levels inherent in ion trapped qubits. It also makes the processor chip more amenable to being built with semiconductor fabrication processes, which is where Infineon Technologies can help. By leveraging Infineon’s precision semiconductor manufacturing capabilities, they can create qubits which are predictable, repeatable, and reliable. The companies have aggressive development plans. The first Oxford Ionics device is slated to be available on the cloud by the end of 2022, with scaling to hundreds of qubits within the next two years. And within five years, Oxford Ionics vision to to have available supercomputing clusters networked together with a quantum networking technology providing computational capability of hundreds or thousands of qubits.
