A major loan facility for the Albanese government’s $1 billion scheme to build a quantum supercomputer in Brisbane is yet to be drawn down, prompting the Coalition to claim US-based start-up PsiQuantum has missed project milestones, casting more doubt on the project.

It was revealed during Senate estimates last week that $275 million in federal loan funding earmarked for the project was yet to be drawn down and PsiQuantum had told the government’s export finance body it was still “working through” conditions to satisfy financing.
