Archer materials AXE has manufactured two proof-of-concept electrical devices to improve the data output of its spin materials and enhance development of its 12CQ quantum computer chip.
The devices were created and characterised by Archer’s quantum team in partnership with academic researchers at the University of New South Wales using simulation software developed by US-based Sonnet Precision Electromagnetics.
Complementary circuits
The Archer team developed complementary superconducting spin readout circuits consisting of up to eight resonators, each capable of simultaneously outputting separate electron spin materials.
They used the simulation software to optimise resonator design and performed measurements over three campaigns that involved testing superconducting readout circuits at temperatures below -269 degrees Celsius and magnetic fields of up to 1.5 tesla.
The innovation is expected to move Archer closer to scaled manufacture of the 12CQ chip, which aims to enable quantum computing for use in mobile applications.
Archer executive chair Greg English said the 12CQ project continues to make significant steps towards the quantum chip's functionality.
“To be functional, the chip needs to be able to detect the input of quantum information and output or display it—known as control and readout, respectively.”“These two proof-of-concept electrical devices bring us closer to the reading out of electron quantum spin information and bolster the manufacturability of the qubit material.”
Next computing phase
Mr English said the development was an example of Archer and its partners conducting important work to bring the next phase of computing to life through the 12CQ quantum chip.
“There is currently a great need for commercial quantum devices,” Mr English said.
“Society is on the cusp of moving from traditional to quantum computing, forced by the rise of artificial intelligence and the algorithms that drive AI need quantum computing power.”
