A team led by UNSW scientists have significantly increased the coherence time of a spin-orbit qubit in silicon, allowing them to preserve quantum information for longer. These results open up a new pathway to scale silicon quantum computers.
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.
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.
Coinciding with the opening of a new quantum computing laboratory at UNSW by Prime Minister Malcolm Turnbull, UNSW researchers have made another advance towards the development of a silicon-based quantum computer.
