Archer Materials Ltd (ASX:AXE) is trading about 9% higher intra-day after developing a computational quantum mechanical theory that accurately models the behaviour of the qubit material at the core of Archer’s 12CQ quantum computing qubit processor (chip).
The computational models validate the origins of experimentally observed quantum phenomena in the qubit material and allow Archer to predict future quantum behaviour.
Importantly, this achievement is fundamental to the successful development of the chip.
“Provides a sound theoretical footing”
Archer CEO Dr Mohammad Choucair said: “We are effectively deploying capital and resources to streamline our chip build.
“The computational modelling of Archer’s qubit system is a world-first and provides a sound theoretical footing for the 12CQ technology.
“In the global multibillion dollar quantum computing ecosystem this type of theoretical validation is a technological prerequisite and demonstrates that Archer operates under a high degree of certainty in its qubit chip development.
“We can now accurately predict the 12CQ qubit materials’ future behaviour, performance, and overcome potential limitations in device operation from an early stage, to drastically reduce technological risk and assist in moving forward with our partners.”
World-first quantum theoretical validation
Archer is working with world-leading theoretical physicists at the prestigious research institute École Polytechnique Fédérale de Lausanne, Switzerland (EPFL), to computationally model Archer’s unique qubit material.
The results of the work validate Archer’s global competitive advantage in quantum computing processor technology development.
For the first time, advanced computational modelling methods of Molecular Dynamics and Density Functional Theory were used to accurately simulate and confirm previous experimental observations made on Archer’s qubit material.

A - Part of the computational model developed that accurately represents the atom-scale structure of the nanosized qubit material, used for calculating the qubit materials’ electronic properties for the first time including in B the density of states (DOS) confirming the unique metallic-like character of the material which in C can be seen in reality in bulk quantities of qubit material having a metallic shimmer. Properties theoretically determined in A and B validate R&D underpinning Archer’s 12CQ quantum computing technology.
The computational modelling of Archer’s 12CQ qubit materials system forms a key part of the company’s technology development work package focused on qubit control which continues and is on track with the latest successful outcomes.
Archer’s models and methods could strengthen and grow the company’s quantum computing patent portfolio in areas related to future chip operation, e.g. rapid optimisation of the qubit material could allow for greater end-user applications.
The company intends to prepare the results of its work for peer-reviewed scientific publication in an accredited journal to disseminate the technical aspects of the work.
