UNSW scientists have shown that their pioneering single atom technology can be adapted to building 3D silicon quantum chips – with precise interlayer alignment and highly accurate measurement of spin states.
Research teams from UNSW are investigating multiple pathways to scale up atom-based computing architectures using spin-orbit coupling – advancing towards their goal of building a silicon-based quantum computer in Australia.
Hundreds of school students got a rare peek into what life as a scientist could be like, as Professor Michelle Simmons opened the doors of the Centre of Excellence for Quantum Computation and Communication Technology ahead of National Science Week.
Australian scientists have achieved a new milestone in their approach to creating a quantum computer chip in silicon, demonstrating the ability to tune the control frequency of a qubit by engineering its atomic configuration.
The unique Australian approach of creating quantum bits from precisely positioned individual atoms in silicon is reaping major rewards, with two of these atom qubits made to “talk” to each other for the first time.
The race is on to build the first reproducable two qubit gate in silicon - the building block for a scalable silicon-based quantum computer. UNSW Sydney-led scientists have shown for the first time that they can make two precisely placed phosphorous atom qubits “talk” to each other.
Australia is the best place for young people and researchers to pursue what they love and realise their dreams, UNSW scientist and 2018 Australian of the Year Michelle Simmons said in her award speech.
