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.
