Remember that information in the sense of discerning patterns must be said to be subjective, and how might subjectivity — relations with the environment, that particular environment — tie in with ...

Seeing a single photon without destroying it
... Light detection is usually a destructive process, in that detectors annihilate photons and convert them into electrical signals, making it impossible to see a single photon twice. But this limitation is not fundamentalÐquantum non-demolition strategies1±3 permit repeated measurements of physically o ...
