Australia’s $4 billion quantum opportunity In The Media A new roadmap from Australia’s national science agency, CSIRO, outlines a vision to create a thriving quantum technology industry, generating $4 billion dollars annually and 16,000 jobs by 2040. More
Silicon carbide (SiC) is a widely used material in several industrial appliions such as high power electronics, light emitting diodes, and in research appliion such as photo-voltaic and quantum technologies. As nanoparticles it can be synthetised in many sizes
At this point, much of the academic research was focused on fundamental quantum physics and quantum computing. However, in 2008 work taking place in the group of Wrachtrup – who was now at the University of Stuttgart, Germany – and in Mikhail Lukin and Ron Walsworth’s groups at Harvard University in the US, proposed and showed that diamond could be used to make a magnetic sensor, in
The university has set up a company, Silicon Quantum Computing Pty Ltd, with investments from Telstra, Australia’s Commonwealth Bank and the Australian and New South Wales governments.
