Archer Materials is an Australiansemiconductor technology company aiming to develop a carbon-based qubitmaterial capable of operating under practical conditions. The qubit is based ona novel nanomaterial in the form of spherical carbon ‘nano onions’ – highlydisordered graphitic structures metallic-like properties. Conduction electronsdelocalized over the volume of the spheres exhibit spin-lattice and spin-spinrelaxation times of 175 ns at 300 K, which is remarkably long for anyconducting solid-state material. The talk will give an overview of Archer’searly-stage progress towards developing the material into a viable qubitarchitecture and discuss potential avenues for collaboration with academicpartners towards this goal.
Dr Martin Fuechsle leads Archer’s quantumtechnology development and is an Hon. Associate of the University of Sydney. Hejoined Archer in 2019, and his work focuses on developing a carbon-basedquantum processor as part of Archer’s 12CQ technology. He has10 years’ experience in building quantum computing devices and technology.During his post-doctoral research at the UNSW Centre for Quantum Computationand Communication Technology he developed the single-atom transistor. Hereceived his PhD in Experimental Physics at the University of New South Walesin 2011, where he worked in Prof. Michelle Simmons’ group on the fabrication ofdonor-based quantum logic devices in silicon.
