Noise is a major obstacle to building large-scale quantum computers. To tame the noise (interference
The work of Dr. Robin Harper and his colleagues,published today, allows the development of algorithms that will work on large quantum devices. They demonstrated this by diagnosing noise in an IBM Quantum Experience device, detecting correlations in a 14-qubit machine. They were previously undetectable.
The results are the first implementation of provably rigorous and scalable diagnostic algorithms that can be run on modern quantum devices and beyond, the scientists emphasize.
The discovery was made by Dr. Harper, a researcher at the University of Sydney Nano Institute and a member of the Australian Research Council's Center of Excellence for Engineering Quantum Systems.
