Quantum computing a step closer to reality

Physicists at The Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment.

Lead researcher Jesse Everett said controlling the movement of light was critical to developing future quantum computers, which could solve problems too complex for today’s most advanced computers.

“Quantum computers based on light – photons – could connect easily with communication technology such as optic fibres and have potential applications in fields such as medicine, defence, telecommunications and financial services,” he said.

The research team’s experiment – which created a light trap by shining infrared lasers into ultra-cold atomic vapour – was inspired by Mr Everett’s discovery of the potential to stop light in a computer simulation. ”

Our method allows us to manipulate the interaction of light and atoms with great precision,” said Associate Professor Buchler from ANU’s Research School of Physics and Engineering.

The research was supported by funding from the ARC Centre of Excellence for Quantum Computation and Communication Technology.

It involves ANU, University of New South Wales, University of Melbourne, University of Queensland, Griffith University, University of Sydney, Australian Defence Force Academy, along with 12 international university and industry partners.
