Archer Materials says the supercomputer analysis will support the development of more complex quantum devices required for the future operation of the 12CQ chip technology.


Archer Materials (ASX: AXE) has validated the uniqueness of its 12CQ quantum computing qubit material (12CQ material) after analysing it using some using some of the world’s most powerful supercomputers.

According to Archer, the complex atom-structure of the 12CQ material requires the “enormous power” of supercomputers for predictive modelling and realistic simulations of its properties.

The company is working with what it describes as world-leading theoretical physicists at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. The work aims to computationally model Archer’s 12CQ material.

“Archer’s development strength has advanced to a stage that calls for high-power computing facilities, and draws on the few people and institutions in the world that can perform this type of work,” Archer chief executive officer Dr Mohammad Choucair explained.

“Supercomputers are powerful tools, and with them, Archer and colleagues at EPFL have run important simulations on the 12CQ qubit material more realistically and more efficiently than ever before, which would never be possible with theory and experimentation alone.”

Supercomputer simulation

Evaluation of the 12CQ material involved quantum chemistry simulation, which used a density-functional tight-binding (DFTB) method.

This essentially involved a combined density function theory and tight binding model of the 12CQ material at the atom-scale.

A density of states (DOS) calculation was used to measure the available electrons that can contribute to the physical processes within a material at a given energy.

In Archer’s 12CQ material, the DOS pinpointed the physical origins of the observed metallic-like properties.

“The results of the work validate Archer’s unique qubit material properties, including confirming an intrinsic metallic-like character of the qubit material,” Dr Choucair said.

“This directly translates to supporting the material structure-property paradigm that gives way to the quantum properties described in Archer’s internationally patented qubit technology architecture,” he added.

During the testing, the supercomputer models increased the simulation capacity of the material system more than 10-times that any previously modelling that Archer or EPFL had undertaken.

“The simulations will be used to support the design and development of the more complex quantum devices required for the future operation of the 12CQ chip technology,” Dr Choucair said.
