Quantum control measurements on Archer’s unique qubit components will be performed at world-class institutes in Sydney over the next six months as part of the overall fabrication process roadmap.
The successful completion of the control measurements would be major validation of the commercial viability of the 12CQ chip.
Major technology milestone
Archer CEO Dr Mohammad Choucair said: “Achieving control of single and few qubits in our 12CQ chip design components would mark our first major technology development milestone in chip operation and a paradigm shift in the wider quantum computing economy that thrives on and values such disruptive advances.
“The company’s recent successful and oversubscribed share purchase plan means we have been able to accelerate 12CQ work programs to significantly reduce the time previously allocated for control fabrication, from 12 months to around 6 months, and has provided the opportunity to rapidly de-risk chip development, which we have commenced.”
Qubit control measurements
Qubit control is an integral part of the 12CQ chip operation and involves accessing and processing quantum information residing on individual and few qubits.
This is directly linked to chip operation, unlike previous ‘measurements’ of single-qubit conductivity which were successfully performed and are directly linked to device integration.
The speciality qubit control instrumentation has now been received from suppliers in the US, configured, and integrated into the measurement systems which have been custom-designed, and purpose-built for this work, together with qubit control software for the instrumentation which has been developed and tested.
Validating commercial viability
Controlling quantum information residing on individual qubits is a key componentry requirement for a working quantum computing qubit processor, another being readout.
Control must be performed prior to readout as these subsequent steps represent a logical series in the 12CQ quantum computing chip function.
The control measurements related to the 12CQ chip fabrication are a world-first, for solid-state, non-optical quantum computing systems.
Successful completion of the control measurements is a major factor in validating the commercial viability of the 12CQ chip technology as qubit control is what allows for operation, function, utility and performance.
The company’s technology development is currently focused on achieving quantum control of a single qubit, that is essential for quantum information processing.
Over the next six months, Archer will perform quantum measurements and materials characterisation at different laboratory facilities to achieve quantum control, and key measurements will be released to ASX.
The control measurements will be performed in parallel to other technology development work packages, intellectual property prosecution and commercialisation.
