Archer Materials Limited, an Australian semiconductor company, has made a significant breakthrough in quantum technology by developing two proof-of-concept electrical devices that improve the readout of its 12CQ quantum chip spin material. The devices consist of up to eight superconducting resonators, each capable of simultaneously reading out separate electron spin material. This development brings the company closer to enabling quantum computing for use in mobile applications.
The achievement builds on Archer’s recently developed next-generation film-based spin material, which improves manufacturability and potentially provides longer spin lifetimes. Greg English, Executive Chair of Archer, commented that the devices bring the company closer to reading out electron quantum spin information and bolster the manufacturability of the qubit material. The development is a result of collaboration with academic researchers at The University of New South Wales and US-based software company Sonnet Precision Electromagnetics.
Improving Quantum Chip Spin Detection: Archer’s Breakthrough
Archer Materials Limited has made significant strides in advancing its 12CQ quantum chip spin material by manufacturing and characterizing two proof-of-concept electrical devices. These devices are designed to improve the readout of the spin material, a crucial step towards developing functional quantum computing technology for mobile applications.
The two complementary superconducting spin readout circuits consist of up to eight resonators, each capable of simultaneously reading out separate electron spin material. This development builds on Archer’s recently developed next-generation film-based spin material, which enhances manufacturability and potentially provides longer spin lifetimes. The devices demonstrate sufficient resilience to high magnetic fields at extremely low temperatures of -269 degrees Celsius.
The quantum team at Archer utilized simulation software developed by Sonnet Precision Electromagnetics to optimize the resonator design and performed measurements over three campaigns. These tests involved evaluating superconducting readout circuits at temperatures below -269 degrees Celsius and at magnetic fields of up to 1.5 Tesla. The collaboration with academic researchers at The University of New South Wales further solidified the results.
This breakthrough provides the necessary groundwork for future measurement of very small quantities of Archer’s quantum spin material, potentially down to a single CNO (Carbon-Nitrogen-Oxygen). The ability to detect and read out electron quantum spin information is a critical component in developing functional quantum computing technology. Archer’s Executive Chair, Greg English, emphasized that this development brings the company closer to achieving control and readout capabilities, essential for the 12CQ project.
Enhancing Manufacturability: Next-Generation Film-Based Spin Material
Archer’s next-generation film-based spin material is a significant advancement in improving manufacturability. This new material enables enhanced precision alignment markers, allowing for nanometer-level precision during device fabrication. The material also exhibits significantly decreased electrical resistance and potentially increased spin lifetimes.
