How would you read the state? If, at the lowest energy state, there is no energy output, would even photons change the state? If so how would you read the "time" from it?
Does that make any sense?

I honestly have no clue either, but they hint at entanglement, and they don't seem to be worried about observation: "Peng Zhang, another co-author and member of Zhang's research group, notes that a space-time crystal might also be used to store and transfer quantum information across different rotational states in both space and time."
