iqClock

Consortium aiming to boost the development of optical clocks using quantum technology. Funded by the European Quantum Flagship Initiative.

iqClock is a 3-year European project made up of research institutes and companies to develop a competitive European industry for optical clocks as well as strengthening and accelerating the pipeline of clock development.

In October 2018 iqClock was chosen as part of the European Union's Quantum Flagship initiative receiving €10,092,468.75 in funding.

Atomic optical clocks are the most precise time-telling tools. However, their size and complexity restricts them for use in the laboratory. The iqClock project aims to use superradiant lasers to produce new robust, compact, portable and commercially viable atomic optical clocks.

These new clocks have potential applications in many fields such as:

  • Telecommunication - network synchronization, traffic bandwidth, GPS free navigation
  • Geology - underground exploration, monitoring of water tables or ice sheets
  • Astronomy - low-frequency gravitational wave detection, radio telescope synchronization

Tasks

The iqClock project is broken down into 4 tasks, each advancing a particular optical clock technology.

Task 1 - Integrated optical lattice clock

Constructing a compact, transportable Strontium optical lattice clock.

Task 2: kHz-line superradiant clock

Demonstrating the cavity-enhanced atom-light coupling can lead to more compact and robust clocks using superradiant emissions.

Task 3: mHz-line superradiant frequency standard

Operating a superradiant clock continuously on a mHz-linewidth clock transition.

Task 4: Superradiant laser foundations

Exploring the foundations of superradiant lasers, the behavior of an ensemble of atoms coupled to a cavity.
