 The Hitachi Cambridge Laboratory, which
is part of Hitachi's global research activities, carries
out research in collaboration with the Microelectronics
Research Centre of Cambridge University, and is located
at the Cavendish Laboratory. Hitachi Cambridge Laboratory
creates new concepts for future electronic and optical devices,
characterises real device structures and specialises in
advanced device concepts and measurement techniques. Recent
successes include innovations in the fields of single electron
memory and logic, coherent optoelectronic control, quantum
information processing and the new PLEDM memory structure
which is currently under development. The combined resources
within the collaboration provide a laboratory which is well
equipped with facilities for nanofabrication with electron
beam lithography and other techniques, low temperature electrical
measurements, ultrafast optical measurements and advanced
numerical simulation to characterise nanoscale devices and
circuits. Very close links exist with other Hitachi research
laboratories in Japan and elsewhere.Quantum Information Processing (QIP) is a new information
technology based on the principle of quantum mechanics.
The principles of quantum measurement is used to ensure
secure information transfer for key exchange etc. Quantum
entanglement is used to perform ultrafast computations such
as factoring large numbers and sorting massive databases.
Nanoelectronic devices made with electron beam lithography,
and molecular constructions such as carbon nanotubes are
utilised as a quantum bit (qubit), a key building block
for the QIP systems.
