What is something that blew your mind as a quantum science researcher ?

SR: Personally, that would be the violation of Bell's inequality, which forces you to either give up on locality (causality) or objective reality. We tend to give up on the latter because we don't know what the world would be like otherwise.

NL: I was trying to cool down a single atom when I learned that the concept of temperature does not apply to a single particle.

Do you guys just put the word quantum in front of everything?

NL: I don't quantum think so.

[From the room]: You haven't seen Ant-Man?

What is the most misunderstood part of quantum science?

NL: Some people think that no one really understands it, but in reality we understand it enough to do quantum engineering now. We understand it as much as we understand other areas of science.

Will we ever beat the speed of light for communication and perhaps travel?

SR, NL, AK: No.

What’s the most contentious theory in your field presently?

NL: It's a bit technical, but in my field there's an argument over whether variational quantum algorithms (a quantum computer running an application that is controlled by a classical optimizer) can be used to solve problems of practical value.

AK: As far as I can tell, the biggest fight is over whose qubit is best.
