30th European Frequency and Time Forum

Satellite workshop

On Friday 8th April 2016, the University of York will be hosting the following satellite workshop to EFTF:

Optical clocks: quantum engineering and international timekeeping

The workshop is organised by two EMRP project consortia: International timescales with optical clocks (ITOC) and Quantum Engineered States for Optical Clocks and Atomic Sensors (QESOCAS). Complementing the scientific programme of EFTF, it will address recent developments related to the use of quantum engineered states to enhance the stability of optical clocks, as well as progress made towards using optical clocks for international timekeeping. Two invited talks from leading experts in the field will be followed by presentations from members of the two project consortia. Poster presentations from all participants are welcomed for the afternoon session.


Registration for this one-day workshop has now closed.

The workshop is free of charge and lunch will be provided.
