Toshiba's LX QKD system provides customisable options for channel wavelengths, alongside the ability to
multiplex the required service channels onto your existing fibre architecture. That means only a single
dedicated QKD fibre is required to make existing networks quantum-safe.
All Toshiba QKD systems use an efficient implementation of BB84, the first and most rigorously studied QKD
protocol, proven secure through years of research. The BB84 protocol provides inherent protection from quantum
computers and any future advances in mathematics.
Incredibly Stable. Incredibly Reliable.
At Toshiba, we've pioneered active stabilisation technology that allows our QKD systems to distribute key
material continuously, in challenging operating conditions, without any user intervention. This avoids the
for recalibration of the system due to temperature-induced changes in the fibre lengths.
The reliability and stability of our QKD systems has been demonstrated in numerous deployments. In fact, at a
theoretical level, the probability of key failure using our technology is <
1 x 10-10 – equivalent to less than once every 30,000 years.
SEE HOW IT WORKS
Fast and cost-effective
LX is Toshiba's most affordable QKD system, but as well as its enhanced service channel flexibility, it's also
remarkably powerful providing 150 kb/s secure key rates and 24 dB optical loss budget.
Toshiba's FleXible QKD System offers markedly simple installation and setup. Once positioned in a standard 19"
rack mount, the QKD hardware offers automated start-up and real-time optimisation, thanks to active
stabilisation technology. Service channels are presented via three separate outputs, so they can be integrated
as required within your existing data-carrying network.
…and easy operation
A user-friendly interface, accessed through a web-browser, provides real-time and historical performance data.
Key management & delivery system
Toshiba’s REST-based Key Management System provides efficient and reliable key storage and delivery. It uses
ETSI industry standards, so it's compatible with leading encryptor vendors and other applications.
