The Albanese government’s giant bet on US-based quantum computing firm PsiQuantum involved an equity investment of $US125 million ($189.5 million) with the rest of the $470 million deal comprising debt, The Australian Financial Review can reveal.

The details of the deal, which was made alongside a matching $470 million commitment by the Qld government, have been withheld until now, but the government’s export credit agency, Export Finance Australia, has now officially signed the contracts with PsiQuantum.
