A new technique by researchers at Princeton University, University of Chicago and IBM significantly improves the reliability of quantum computers by harnessing data about the noisiness of operations on real hardware. In a paper presented this week, researchers describe a novel compilation method that boosts the ability of resource-constrained and “noisy” quantum computers to produce useful answers. Notably, the researchers demonstrated a nearly three times average improvement in reliability for real-system runs on IBM’s 16-qubit quantum computer, improving some program executions by as much as eighteen-fold.
