Archer Materials secures Hong Kong patent for quantum computing chip technology
Archer Materials now has exclusive and legally enforceable commercial rights for its 12CQ chip technology in Hong Kong, Australia, the US, China, South Korea, Japan and 12 countries in Europe.
Archer Materials (ASX: AXE) has added another patent to its portfolio with the official grant of a Hong Kong patent for its quantum computing chip technology (12CQ chip).
The Hong Kong patent was the final pending application and follows existing patents for the 12CQ chip technology in Australia, the US, China, South Korea, Japan and a further 12 countries in Europe including the UK, France and Germany.
Archer chief executive officer Dr Mohammad Choucair said securing the Hong Kong patent for the 12CQ chip was “great news” for the company.
“A patent is evidence of invention, and patent protection in major markets is a central element in Archer’s strategy to develop the 12CQ chip.”
Dr Choucair added the patent granting process for the 12CQ chip has been an “outstanding success”.
“Archer is one of the few companies with granted patents protecting quantum computing chip technology, and one with a unique global competitive advantage,” he said.
Possessing patents gives Archer exclusive and legally enforceable commercial rights in all the abovementioned jurisdictions.
12CQ chip technology
The company describes its 12CQ chip as a world first qubit processor technology – potentially enabling quantum computing-powered mobile devices.
In developing the technology further, Archer has fabricated nanodevices that will allow probing of quantum behaviour in its qubit material.
This is of “fundamental importance” to the 12CQ chip technology operation.
According to the company, “significant innovation” is required to produce nanodevices.
Archer’s fabrication of nanodevices is the first step to the readout of quantum states from few and single qubits used in its 12CQ chip technology.
To enable nanofabrication, Archer used state-of-the-art lithography and specialised software. This allowed the company to obtain feature sizes compatible with a few to single qubits.
Archer noted its fabrication process is reproducible at scale – solving challenges related to complex nanodevice proximity effects and the on-chip integration of micron and nanometre size features.
