| Abstract | The Bristol free space Quantum Key Distribution (QKD) system offers a potential solution to possible future security problems. Within the Bristol QKD system there is no shared clock between Alice, intended to be a mobile phone chipset and Bob the Quantum Automatic Teller Machine (QATM). Therefore instead of sharing a clock, a Timing Interval Analyzer is used to timestamp all incident photons in Bob. As Alice's repetition rate is fixed and known, it is possible to distinguish Alice's photons from that of dark counts and ambient light. The TIA produced in house to do this time stamping process has a resolution of 30.5 picoseconds and a single shot RMS measurement error of 35.2 picoseconds, whilst using off the shelf components. Although the TIA is used within a QKD system it has wider applications within other photonics experiments in particular that of time correlated single photon counting (TCSPC). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
