Q-CTRL is an Australian start-up that builds quantum control infrastructure software, with a focus on developing tools and techniques for error suppression. Q-CTRL’s approach applies the principles of control engineering to accelerate quantum computing technology.
This is a particular obstacle in quantum computing. While there is considerable excitement about the possibilities of quantum information and quantum computing applications – spurring billions of dollars of investment around the world – many technical hurdles have yet to be crossed. Most quantum computers are so prone to error that only the shortest, simplest algorithms can be run. When Q-CTRL experimented with algorithmic hardware systems, building on recent benchmarking experiments from the US Quantum Economic Development Consortium, the errors it encountered were initially so severe that the computers in some cases returned outputs no better than random chance.
