Archer Materials at new record on key 12CQ milestone with electronic transport achieved in a single qubit

The work represents a significant technical achievement because the electronic transport measurements were performed on a single qubit – only a few hundred atoms across – and at room temperature.

An individual qubit about 50 nanometres in size between two probe tip surfaces a few hundred atoms apart, which then serve as electrical contacts to perform electronic transport measurements.

Archer Materials Ltd (ASX:AXE) (OTCMKTS:ARRXF) (FRA:38A) hit a new record high after passing a key technological milestone with electronic transport achieved in a single qubit at room temperature.

This work forms part of Archer’s 12CQ quantum computing qubit processor chip technology development.

It represents a significant technical achievement because the electronic transport measurements were performed on a single qubit – only a few hundred atoms across – and at room temperature.

New record high

Shares surged 55 per cent to A$1.24 intra-day, a new record high for the company which has a market cap of approximately A$180.5 million.

The company utilised more than A$150 million of semiconductor foundry facilities and some of the most advanced instrumentation in the world to complete its most recent validation of the 12CQ technology.

“Pushing the boundaries”

Archer CEO Mohammad Choucair said: “In building our 12CQ chip for room temperature operation and integration onboard electronic devices, we are pushing the boundaries of what can be done technologically in the world today.

“The importance of achieving electronic transport in a single qubit at room temperature cannot be overstated as it will have a positive and broad impact on the development of the 12CQ chip.

“The work unambiguously shows that a single qubit – the fundamental quantum information containing a material component of the 12CQ chip – could be used to build ‘gated’ semiconductor devices.

“This is great news and direct technological validation for both the fabrication and operation of the 12CQ chip.

“Archer is working with the few people and institutions in the world that have the know-how, facilities, and instrumentation to drive our development forward at pace.

“The greatest amount of value creation in the quantum computing economy is currently generated from technology development like that which has been achieved here.”

Core component of 12CQ chip

Archer successfully performed the direct measurement of the room-temperature two-terminal resistance of the qubit material, which is the core component of the 12CQ chip.

Current-volage traces were repeatedly and reproducibly recorded over various voltage range on single isolated qubits, two-qubits and qubit clusters.

The qubits were advantageously robust and withstood damage or change in an electronic structure during measurement.

Outcomes provide the necessary quantitative data and component-level information that directly validate the ability of the qubits to operate within the electronic parameters required for functional, gated semiconductor devices at room temperature.

Commercial advantage

This represents a significant commercial advantage over competing for qubit chip device proposals.

It demonstrates that the company continues to successfully operate under a high degree of scrutiny in its qubit chip development and commercialisation.

Archer is currently performing quantum measurements and materials characterisation at different laboratory facilities that form a part of the company’s technology development work package focused on ‘qubit control’.
