| Nov 1, 2012 at 12:41 | comment | added | Mark Mitchison | Under unitary operations, information (entropy) is conserved. However, the uncertainty principle is about the quantum measurement process, which manifestly does not conserve information because quantum states change discontinuously and irreversibly. | |
| Nov 1, 2012 at 12:24 | comment | added | TMS | @Mike: do you pointing to that Info. conservation is due to reversibility, not due to CPT? aren't they connected at the end? | |
