What if quantum computers already broke Bitcoin?

“Everything would look like legitimate access,” David Carvalho, CEO of post-quantum infrastructure company Naoris Protocol, told Cointelegraph. “When you think you’re seeing a quantum computer out there, it’s already been in control for months.”
“You wouldn’t even know,” he said.
