Toshiba Research Europe Limited (TREL) is based in Cambridge in the UK where it has been researching applications of quantum physics to information technologies for 25 years (as of 2016).

TREL participates in technical work-package WP1, to which it brings expertise in the design, characterisation, and operation of high bit rate quantum key distribution components and systems for fibre-optic networks. Work undertaken will examine implementation security and the associated metrology of quantum systems in the context of standardisation efforts that are being pursued within the Industry Specification Group on QKD of the European Telecommunications Standards Institute (ETSI).
