I always understood that QKD is based on a hard problem of which the theory of
physics says it is impossible to find a solution (if not, then i'd like to
know). Then if QKD breaks, the current theory of physics was wrong.
On the other hand, if DH or RSA breaks, factoring or the discrete log turn

Peter Fairbrother may well be in possession of a break for the QC hard
problem - his last post stated there was a way to clone photons with
high accuracy in retention of their polarization

Dumb question. Why is the bad guy called Mallory in
this thread? I always thought that traditionally the
two correspondents were called Alice and Bob and that
the bad guy was called Eve. (As in, short for eavesdropper?).

The Cyrillic Projector is an encrypted sculpture at the
University of North Carolina in Charlotte, that was created by
Washington DC artist James Sanborn in the early 1990s. It was
inspired by the encrypted Kryptos sculpture that Sanborn created
two years earlier for CIA
BTW, you can decrease the wavelength of a photon by bouncing it off
moving
mirrors.
Sure. To double the energy (halve the wavelength), move the mirror at
70% of the speed of light. And since you don't know exactly when the
photon is coming, keep it moving at that speed ...

Well, that's the question - is Eve allowed to
forward packets, in the act of listening, or
is that the Mallory's job? I don't know.
You can't measure a single-particle state without at least some chance
of destroying the state. (Even quantum non-demolition methods affect
the measured system a
