BBN Technologies Develops High Speed
Quantum Cryptography
BBN
Technologies has successfully demonstrated a high speed
single-photon superconducting detector designed for
standard telecommunication fibers for applications in
quantum cryptography (QC) networks. Laboratory trials
by BBN have reportedly confirmed continuous operation at
100 million pulses per second.
Before now, detectors have been a terrible bottleneck
in the effort to expand the capabilities of QC
networks. Our system runs 20 times faster than typical
benchmark systems, said Jonathan Habif, Head Scientist
of the BBN detector team.
The
detector is based on a niobium nitride hot electron
bolometer (HEB) operating at 10GHz. It is cooled to
about 3K with a closed-cycle liquid cryogen-free
cryocooler designed by NIST.
