Why is Quantum Science Disturbing

The physical nature of information
... But we cannot, in general, tell whether two arbitrary quantum states differ, or not. Even if we were able to recognize errors, we cannot throw away the description of the error. Discarding information is a dissipative event and will spoil the coherence needed for quantum parallelism. If we do keep a ...
