September 3, 2024 -- Archer Materials Limited, a semiconductor company focused on quantum technology, has made recent strides in the development of its 12CQ quantum chip. According to their latest announcement, Archer has successfully produced two proof-of-concept devices designed to enhance the spin detection capabilities of the chip, relevant to integrating quantum computing with mobile devices.

Archer’s newly developed devices feature superconducting spin readout circuits, each equipped with up to eight resonators, and incorporate next-generation film-based spin material, enhancing manufacturability and potentially extending spin lifetimes. These circuits are integral for detecting electron spin material, a critical element in quantum information processing. Engineered to endure extreme conditions, the circuits demonstrated resilience at cryogenic temperatures of -269 degrees Celsius and in high magnetic fields up to 1.5 Tesla, a necessary durability for the practical deployment of quantum computing technologies.

The development of these devices is a significant milestone for Archer. Greg English, Executive Chair of Archer, emphasized the importance of this progress, “To be functional, the chip needs to be able to have the ability to detect the input of quantum information, and output information, or display it, known as control and readout, respectively. The two proof-of-concept electrical devices brings us closer to readout, or the reading out of electron quantum spin information, and bolsters the manufacturability of the qubit material.”

Archer’s success in developing these proof-of-concept devices is supported by strategic partnerships, including collaboration with The University of New South Wales and the use of simulation software from Sonnet Precision Electromagnetics. These collaborations have been instrumental in optimizing the design and functionality of the superconducting circuits.

Archer Materials’ recent progress in quantum chip spin detection reflect the company’s commitment to developing advanced quantum computing technologies, as well as continuing its leadership in the semiconductor industry to bring quantum computing closer to everyday mobile devices.
