- The NPL caesium fountain atomic clock (NPL-CsF2) has been declared accurate to one second in 158 million years.
- Happy 90th Birthday to BBC Radio's 'time pips'.
- The European Physical Society (EPS) names NPL the birthplace of atomic timekeeping.
'Quantum' refers to the minimum amount of a physical entity. A photon is a quantum, for example, as it is the smallest divisible unit of light: a single light particle.
Quantum physics describes the behaviour of small particles, including photons, as well as atoms, ions and electrons. The wave-like behaviour of quantum systems gives rise to many interesting properties that can be exploited in areas such as computing, communication and timing.
Several research groups at NPL are currently working on advancing quantum technologies. A new facility, the Advanced Metrology Laboratory, will build on NPL's expertise to enhance the UK's capabilities in developing and applying these exciting technologies.
