EeroQ has developed new microwave resonators designed to enhance the speed and accuracy of qubit readout in its electrons-on-helium quantum computing platform. Published in Physical Review Applied, the research demonstrates resonators fabricated using titanium nitride, a superconducting material with high kinetic inductance, which significantly improves measurement speed. The resonators integrate seamlessly with EeroQ’s CMOS-based quantum devices and exhibit microwave responses accurately predicted by theoretical models, validating their reliability.
These advancements build on the principles of circuit quantum electrodynamics (cQED), a foundational technology for modern quantum computing. By leveraging cQED, EeroQ’s resonators enable fast, accurate, and space-efficient quantum information processing. The design allows a single resonator to read out multiple electron qubits, reducing the number of physical readout devices required per quantum computer.
Developed in collaboration with the University of Chicago and Stanford University, this innovation marks a significant step toward scalable quantum computing. EeroQ’s approach combines the inherent scalability of electrons-on-helium systems with advanced readout technology.
