Archer Materials has early-stage validation of quantum computing chip viability

“Directly proving room-temperature conductivity of the 12CQ chip qubit component solidifies our global competitive advantage and advances our development towards a working chip prototype,” says CEO Dr Choucair.

Archer Materials Limited (ASX:AXE) has passed a major technological milestone with early-stage validation of the viability of its 12CQ technology that aims to build a room-temperature quantum computing qubit processor (chip).

State-of-the-art measurement has confirmed room-temperature conductivity of a single qubit component, representing a global competitive advantage in the multi-billion-dollar quantum computing industry.

The room-temperature conductivity potentially enables direct access to the quantum information stored in the qubits.

"Towards a working chip prototype"

Archer CEO Dr Mohammad Choucair said: “We have successfully performed our first measurement on a single qubit component, which is the most important component, marking a significant period moving forward in the development of Archer’s 12CQ quantum computing chip technology.

“Building and operating the 12CQ chip requires measurements to be successfully performed at the very limits of what can be achieved technologically in the world today.

“Directly proving room-temperature conductivity of the 12CQ chip qubit component solidifies our global competitive advantage and advances our development towards a working chip prototype.”

Room-temperature conductivity measurement

Shares have been more than 17% higher to 70.5 cents intra-day and have risen from 42 cents at close on May 19.

Conductivity measurements on single qubit components were carried out by Archer staff using conductive atomic force microscopy that was configured using state-of-the-art instrumentation systems and housed in a semiconductor prototype foundry cleanroom.

Electron microscope image of the pre-patterned test-bed device that was purpose-built for the measurements and provided direct proof of single qubit conductivity.

The measurements directly and unambiguously proved, with nanometre-scale precision, the conductivity of single qubits at room-temperature in ambient environmental conditions (eg in the presence of air, moisture and at normal atmospheric pressures).

Wider commercial impact

Qubit conductivity and associated underlying theories were proposed in 2016 by Archer CEO Dr Choucair, in the seminal work underpinning the 12CQ technology published in the highly reputable peer-reviewed scientific journal Nature Communications.

The measurements have now directly, unambiguously and reproducibly confirmed these proposals, which are major factors in determining the commercial viability of the 12CQ chip technology.

These measurements progress Archer’s technological development towards controlling quantum information residing on individual qubits, which is a key componentry requirement for a working quantum computing qubit processor; another being readout.

Control must be performed prior to readout, as these subsequent steps represent a logical series in the 12CQ quantum computing chip function.

World-first technology

12CQ is a world-first technology that Archer aims to build for quantum computing operation at room-temperature and integration onboard modern electronic devices.

Archer maintains an exclusive licence to all the intellectual property rights related to the 12CQ chip technology, including the trade secrets resulting from the measurements, and patent applications filed under the Patent Cooperation Treaty (PCT) to protect and commercialise intellectual property in Australia, China, Japan, South Korea, Hong Kong, European Union, and the United States.

The international PCT application continues to progress in all jurisdictions at various stages of the patent granting procedure.
