Highlights: In a fireside chat with Gary Tan at Y Combinator’s AI Startup School that was posted on YouTube on Wednesday, Microsoft CEO Satya Nadella said that it will be a game-changer when quantum computing is integrated with AI. 

“If you want to understand the language of nature, which is simulation, I think the best way to do it is through a quantum computer because, after all, physics and nature are quantum,” Nadella said. 

“What we are seeing is pretty good advances in using basically HPC+AI as a way to accelerate advances in Chemistry, in Physics, in Material Science and so quantum would be the next step in it."

"But we're very excited about what AI+quantum and HPC in a loop can do,” he added.

Lowlights: Quantum Computing shares fell on Monday after the company announced a $200 million private placement with institutional investors.
