Archer Materials Forges Ahead: Quantum Devices Successfully Built for Qubit Control

Quantum devices successfully built for qubit control

Archer Materials Limited (ASX:AXE) has successfully built the quantum devices required for initial qubit control measurements as part of a significant phase in its technology development related to the operation of the 12CQ room-temperature quantum computing qubit processor.

The full ESR device design is commercial-in-confidence.  The ESR device has been fundamentally developed end-to-end and custom-built together by Archer and collaborators in Sydney, Australia, including all quantum mechanical theoretical considerations, the materials formulations used, the device operation, function and purpose, and its fabrication and testing.

Commenting on the Company’s 12CQ chip development, Archer CEO Dr Mohammad Choucair said: “We commenced our technology development related to qubit control a few weeks ago and now the first devices have been built to perform the initial [qubit control] measurements related to Archer’s 12CQ chip operation. We have remained on track in our development since we first commenced the [12CQ chip] project in April 2019.”

“Qubit control is explicitly our next big technological milestone. Over the coming months, Company shareholders will expect to see a series of results that will be released to ASX by Archer that relate to qubit control – a key requirement of quantum computing processors. When successful, the work would be major validation, at a relatively early-stage of the overall development of a quantum computing processor, of the commercial viability of the 12CQ chip”.

The Archer team has built and begun testing prototype qubit control devices (“ESR devices”) in Sydney with collaborating institutes. The initial prototyped ESR device has the primary benefit of providing the magnetic ultra-sensitivity to establish quantitative measurements (i.e. characterisation) of the quantum information residing on very few qubit material components.

The initial ESR device design is intended to allow for qubit control measurements only at low temperatures to maximise the Primary Benefit, with the associated operation temperatures unrelated to Archer’s qubits’ demonstrated potential to operate at room temperature. The ESR device assembly is unique and unoptimised, subject to changing functional configurations. 

Archer CEO Dr Mohammad Choucair concluded: “The control measurements on the qubit material related to the 12CQ chip fabrication are a world-first, in particular for solid-state, non-optical quantum computing systems. 

“Archer is at the forefront of a global race to develop a potential solution to commercially viable [qubit processor chip] technology for the widespread use of quantum computing – technology which is at the foundation of an emerging multibillion-dollar global industry.”
