Archer Materials Ltd progresses 12CQ chip qubit control with advanced device modelling (via Qpute.com)


The company is developing qubit control devices based on various semiconductor technologies that integrate control electronics with 12CQ chip qubits.

() () (FRA:38A) continues to progress the development of its 12CQ quantum computing processor chip by applying advanced semiconductor device modelling to build sophisticated qubit control devices.

Controlling qubits in Archer’s 12CQ chip requires the design of new and highly complex quantum information control electronics to integrate with 12CQ chip qubits.

The company is now at a stage of development where these advanced designs can be (and are being) developed from first principles, modelled using specialised software, built and tested, all in an end-to-end process.

Electromagnetic finite element modelling

The company has now progressed to utilising Electromagnetic Finite Element Modelling to build qubit control devices.

This sophisticated modelling facilitates achieving qubit control of few and single qubits, which are key milestones in validating 12CQ chip viability – without this, 12CQ chip operation would not be possible.

Archer chief executive officer Dr Mohammad Choucair said: “We are progressing with our 12CQ chip development by iterating new qubit control device designs and upgrading existing [control] prototypes to integrate with 12CQ chip qubits.

“Advanced device modelling is required to do this work, especially as we have the opportunity to account for qubit scalability early on, which is a key advantage over other qubit proposals.”

Shares have been as much as 9.2% higher intra-day to A$0.83 while the company’s market cap is approximately A$171.8 million.

Emerging global market

Archer is focused on developing a world-first quantum computing chip and securing the related intellectual property in global markets.

The company is one of only a few players developing a qubit processor chip in the emerging multi-billion-dollar quantum computing industry, with the global market for manufacturing chips is valued at US$400+ billion and estimated to potentially reach US$1 trillion by 2030.

Chips currently address end markets valued at US$4+ trillion, that include processor, sensor and memory devices.

Looking forward

The company’s team and collaborators use semiconductor fabrication processes in a A$150 million research and prototype foundry in Sydney, to build the new and complex qubit control architectures onto a chip integrating the 12CQ qubits.

Testing and optimisation of these qubit control devices is performed using multi-million-dollar, custom-built, qubit control infrastructure.
