14 November 2023 | Quantum computing has long been considered to be the next revolution in computing Quantum computers will, it is claimed, be able to solve complex problems that would take existing supercomputers weeks or months to complete, in a matter of seconds. Alas, up until now, the largest quantum computer has reached only 433 qubits and these computers use massively more power than...

14 November 2023 | In the past few years, National Metrology Institutes (NMIs) have successfully developed and tested new T&F techniques using optical fibres which have shown a stability performance of at least three orders of magnitude better than the current best commercial services. Moreover, such techniques offer an alternative to Global Navigation Satellite System (GNSS) for end-users...
14 November 2023 | Quantum Key Distribution (QKD) provides provably secure protection against attacks by quantum computers on current public key encryption protocols and infrastructures. QKD is being increasingly deployed globally and there are some important considerations for practical QKD deployment in today’s fibre networks. High optical budgets and high Secret Key Rates (SKR) QKD systems...
