Welcome to the Quantum Information Group
Toshiba is developing a new approach to information technology that applies the
fundamental laws of Quantum Physics to network communications and computing.
Quantum Information Technology concerns the transport and processing of information
using individual particles such as electrons or photons. Using single particles
in this way brings unexpected advantages. By sending information encoded upon single
photons (the particles of light) it is possible to test the secrecy of each communication.
Toshiba has exploited this phenomenon to create a practical system for secure communication
over fibre optical cables. However, Quantum Cryptography, as this secure communication
method is known, is just the first in a series of quantum innovations which promises
to revolutionise the entire IT industry over the next two decades.
