Today's resistance thermometers can routinely measure temperatures with uncertainties of >1 mK–100 mK over multiple decades of temperatures. As the modern economy continues to evolve, so does the measurement infrastructure. In recent years, there has been a considerable progress in the development of novel temperature sensing technologies driven by advances in quantum information science and nano-photonics. Quantum technologies in particular hold the promise of field-deployable primary thermometry whilst ultra-stable nanophotonic thermometers could displace resistance thermometers as commodity sensors.

Qubits, Atoms, Photons, Entanglements, Quantum Mechanics and Diamonds meet the Information Age. Current research indicates that diamonds may hold the key to a cryptanalyst's nightmare, 'The unbreakable cipher'. This paper introduces the basic theory and principles behind this innovative technology, reports on the research that has led to present day breakthroughs, investigates those that hold promise and looks at the possibilities for future research in this field. This report is presented as a primer to the 'World of Quantum Cryptography' and its impact on Network Security and Management. Consequently, it does not provide any mathematical proofs behind the theoretical models which relate to Quantum Mechanics. It does, however, make reference to and direct those who require this depth of knowledge to the sources if this information is desired or is the basis for further research.
