Subject: Could freezing light negate Quantum cryptography?

Dave,

This month's IEEE Spectrum article : http://www.spectrum.ieee.org/ 
aug06/4252

to my very amateur mind raises questions about the viability of  
quantum cryptography.

If a photon can be frozen (and I can't say whether their technique  
can be extended
to the photon level) can it be measured in its frozen state?  That  
would make the
difference.
