Archer Materials (AXE) has validated the robustness of its CQ quantum computing chip technology.

The company has gained its first validation that its qubits’ quantum coherence properties are preserved under an inert atmosphere.

“The step change optimisation that was achieved validates the robustness of the qubit for control measurements and operation that could be compatible with device miniaturisation and, in general, preserving qubit coherence when integrating with semiconductor devices,” Archer CEO Dr Mohammad Choucair said.

Quantum coherence is the fundamental requirement for quantum logic operations which are the basis of any quantum computing qubit processor hardware.

In order to allow potential integration into practical chip devices, the qubit should demonstrate and validate robustness both at room temperature and under atmospheric environments other than that of air or vacuum.

The testing to validate the robustness of the qubit took place at room temperature, using electron spin resonance instruments.

Large quantities of the qubit material were subject to inert atmosphere made up of nitrogen gas, which was found to preserve the qubits’ quantum coherence properties.

Archer also found that the quantum properties of the bulk qubit material could be recovered, even after a long shelf-life and when placed under extreme exposure to high temperatures, for at least several weeks.

The Archer team said it was now looking into other inert atmospheres that may preserve the qubits’ quantum properties.

Archer said it was well-funded to progress its 12CQ chip technology development after recently raising $15 million via an institutional placement.

Shares were up 9.09 per cent, trading at $1.62 at 12:08 pm AEDT.
