It is a time-reversed dual to the no-cloning theorem, [1] [2] which states that arbitrary states cannot be copied. It was proved by Arun K. Pati and Samuel L. Braunstein. [3] Intuitively, it is because information is conserved under unitary evolution. [4]
The game calls this place directly so that burned copy with no data beyond file limit cannot be played. PSP (Universal Media Disc) Since no blank media or writer exists, the media itself cannot be copied, but one could make ISO image (a file version of the UMD) on a memory card. The unique format also made the media expensive and difficult to ...
The Compact Disc has a similar "no copy" bit in the subcode, but nearly all disc-copying software ignores it, and usually removes it on copies. Consumer-grade dedicated hardware audio disc copiers usually honor the bozo bit, and will refuse to copy a disc with the bit set. Professional disc copiers ignore the bozo bit and will copy a protected ...
CD/DVD copy protection is a blanket term for various methods of copy protection for CDs and DVDs. Such methods include DRM , CD-checks, Dummy Files, illegal tables of contents, over-sizing or over-burning the CD, physical errors and bad sectors.
In the statement of the theorem, two assumptions were made: the state to be copied is a pure state and the proposed copier acts via unitary time evolution. These assumptions cause no loss of generality. If the state to be copied is a mixed state, it can be "purified," i.e. treated as a pure state of a larger system. Alternately, a different ...
