I read recently in Scientific American about quantum technology being
used in encryption. Basically the idea is that the individual particles
used in the transmission signal are charged or spun at the quantum level
in such a way (without affecting the data itself) that the signal can't
be intercepted or examined without corrupting this charge or spin and
marking the signal as compromised. This got me thinking as to whether an
arbitrary pattern of electrons or light (i.e. an audio file being
transmitted or stored on a medium) could be "tagged" at the quantum
level, thus making it unreadable without proper hardware (or at least
the correct key) and making it useful for DRM purposes. Since the data
itself does not change (just some normally ignored/discarded
characteristics of the transmission signal), it would not affect the
size or performance of the DRM encoded data.
Here's the link:

Of course, if quantum computing were to ever emerge as a viable
technology, this would no longer work since the technique "piggy-backs"
upon existing technology.

There are different kinds of OSS.
Something like GCC or emacs (or POV) is going to be driven by developers who
need their tools.
Something like Open Office is written by a company that doesn't really do
software for a living, but instead wants to undercut the software of a
competitor. In this case, Sun trying to sell Sparcstations without Microsoft
eating their lunch.
Something like Blender is software that was originally in-house until the
developers thought it would be more valuable to make it open source,
primarily because their business changed. (In this case, their business
changed to "out of business", but other changes work too.)

That's the assumption. I am not sure one can tell if it's right or not.

The quantum encryption would continue to work fine. You can't *store*
quantum keys. That's the whole point that makes quantum cryptography work.
Therefore Quantum DRM is not going to happen, at least not using the same
techniques as quantum cryptography.

There probably is - I'm just waiting for you to find it. ;-)

You'll just have to remain mystified.

I shan't waste any more time on it then, if you can't be bothered to
communicate clearly, it's your loss. :-)
