I think a Nobel prize for the second quantum revolution is overdue. The people whose names are most associated with it are Anton Zeilinger, John Clauser, and Alain Aspect. They’ve been on the list for a Nobel Prize for quite some while and I hope that this year they’ll get lucky.Many have been predicting Nobel prizes for these guys. And previously for David Bohm and John Bell, but they are now dead. See Bell test, for a survey of this work.
They have been passed up again this year.
My guess is that the explanation is that they do not give prizes for merely confirming existing knowledge. These experiments had the potential of disproving quantum mechanics, and that is what was driving the work by Bell and others. But they just confirmed the 1927 theory.
They say these experiments prove how strange quantum mechanics, because they show that it cannot be replaced by a local hidden variable theory. But again, that has been the consensus since about 1930. A Nobel prize for this would be like a prize for demonstrating energy conservation.
Some say that the Bell ideas provoked a lot of thinking about quantum information, "it from bit", and maybe even quantum computing.
But the maybe oddest thing to have come out of this is quantum teleportation. Quantum teleportation allows you to send quantum information with entangled states, even if you don’t yourself know the quantum information. ...Dozens of Nobel prizes have been given for quantum theory. I just don't see quantum teleportation as important or interests, either theoretically or practically.
Quantum technologies have a lot of potential that we’re only now beginning to explore.
