Archer Materials Limited (ASX:AXE) has achieved a major breakthrough in electronic transport in a single qubit at room temperature, as part of its CQ quantum computing qubit processor chip (12CQ chip) technology development.
12CQ is a world-first qubit processor chip technology that Archer aims to build for quantum computing operation at room-temperature and integration onboard modern electronic devices.
CEO Dr Mohammad Choucair said this achievement is considered fundamental to the successful development of the 12CQ chip.
Archer successfully performed the direct measurement of the room-temperature two-terminal resistance of the qubit material (qubit), which is the core component of the 12CQ chip. Current-volage traces were repeatedly and reproducibily 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 electronic structure during measurement.
The outcomes of the measurements provide the necessary quantitiative data and component- level information that directly validates the ability of the qubits to operate within the electronic parameters required for functional, gated semiconductor devices at room temperature. This represents a significant commercial advantage over competing qubit chip device proposals.
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,” Mr Choucair said:
“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 unambigiously shows that a single qubit – the fundamental quantum information containing 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.”
