Seeing the quantum future—14 January 2017

Researchers the ARC Centre of Excellence for Engineered Quantum Systems (EQUS), based at The University of Sydney, have demonstrated the ability to ‘see’ the future of quantum systems, and used that knowledge to pre-empt their demise. This achievement could help bring the strange and powerful world of quantum technology closer to reality. The applications of quantum-enabled technologies are compelling and already demonstrating significant impacts—especially in the realm of sensing and metrology. The potential to build exceptionally powerful quantum computers using quantum bits, or qubits, is also driving investment from the world’s largest companies. However, a significant obstacle to building reliable quantum technologies has been the randomisation of quantum systems by their environments, or decoherence, which effectively destroys the useful quantum character. The EQUS team have taken a technical quantum leap in addressing this, using techniques from big data to predict how quantum systems will change and then preventing the system’s breakdown from occurring. The team turned to machine learning for help in keeping their quantum systems—qubits realised in trapped atoms—from breaking.
