After 20 years of research, an encryption process is emerging that is
considered unbreakable because it employs the mind-blowing laws of quantum
physics. In November, a small startup called MagiQ Technologies Inc. began
selling what appears to be the first commercially available system that uses
individual photons to transfer the numeric keys that are widely used to encode
and read secret documents. <BR>MagiQ (pronounced "magic," with the "Q" for
"quantum") expects this will appeal to banks, insurers, government agencies,
pharmaceutical companies and other organizations that transmit sensitive
information. "We think this is going to have a huge, positive impact on the
world," said Bob Gelfond, MagiQ's founder and chief executive. Encryption
schemes commonly used now are considered safe, though they theoretically could
be broken someday. But even before that day arrives, Gelfond believes quantum
encryption is superior in one important way. In some super-high-security
settings, people sharing passwords and other information must have the same
key, a massive string of digits used to encode data. Sometimes the keys will
be transferred by imperfect means -- via courier or special software. They are
not changed very often and can be susceptible to interception. <BR>Quantum
encryption employs one of the defining discoveries of physics: Heisenberg's
Uncertainty Principle, which says subatomic particles exist in multiple
possible states at once, however hard as that may be to imagine, until
something interacts with them.</DIV>
