These quantum machines must be built to know whether they work
“We just have to build these machines and see if they work,” Preskill said.

“Without magic, things are a little too simple. And, you know, quantum space-time isn't quite that simple.”
““We put together a lot of things,” Preskill said. “When you do it right, the answer turns out to be surprisingly encouraging.””
“Preskill, for his part, would like to simulate the quantum nature of space-time.”
“I don’t know of any mundane way to explain it.”
“I thought it was a little bit crazy, but I thought it was the least crazy of all the possibilities.”
“Arora also explains why quantum computers could threaten today's encryption — and why hackers may already be collecting data to decrypt later.”
