Bright sparks: How Griffith researchers are using light to build a better supercomputer

Griffith University researchers are building the next wave of supercomputers.
Work published in Light: Science and Applications shows a new technique for a quick and reliable characterisation of integrated quantum chips that encode information using light instead of electrical current.
In collaboration with ANU, RMIT and UTS in Australia and ITMO University in Russia, the researchers demonstrate a new method for measuring and certifying the quality of quantum devices.
“Such devices will be key for the realisation of an ultra-powerful computer in the near future and are researched by industry leaders like IBM, Google and Microsoft,” said Griffith University researcher Associate Professor Mirko Lobino (pictured), of the Centre for Quantum Dynamics.
“Having a technique to certify the quality of such devices is crucial for the development of this technology on a large scale, and this is what we have done in our paper.
“Since future quantum computers will consist of thousands, if not more, devices assembled together,
