Quantum cryptography - long the stuff of cyberpunk novels and hi-tech spy stories - is leaving the laboratory and making its way into commercial markets. A briefing session at the UK's Department of Trade and Industry on Wednesday featured demonstrations of working quantum key exchange systems by QinetiQ, Toshiba Cambridge and US start-up MagiQ.

port. Conventional Highly Encrypted Data
transmitted in VPN tunnels may be more
cost effective at this point (and has been exhaustively validated).
Another critical metric (besides speed) is
distance. Shorter distances require more repeaters (regenerated timing and signal data) and this is more expensive and
provides a tap point vulnerability (one
photon or not).
Non-US Banks are known for not having very
good security. A more meaningful endorsement
of the technology might come from the us gov or tier1 carriers.
The Fiber Optic Telecommunications Industry
would be very pleased if "Quantum Cypto" resulted in better photon multipliers, wavelength and/or phase discriminators.
Most Industry Experts feel that
the future reides in C-Band and L-Band
DWM/DWDM technology. That coupled with
ADSS (All Dielectric Self Supporting)
Ariel Fiberoptic Cable and Inch Trenches
(small channels cut in sidewalks with
embedded cables), Free Space Optics, etc.
seem to indicate the overall cost of
high speed data transmission will continue
to fall.
Still, 10Gbps and 40Gbps equipment is very
expensive and carefully monitored so
exploiting data in a trunk corridor is
highly unlikely.
www.10GSuperMAN.com (10Gbps Super
Metropolitan Area Network) does conduct
reseach in related areas. Most of the new photonic devices are now coming out of the
EU and Asia is R&D has all but died in the us since the dot com bust.
