Welcome to AQuRA!
AQuRA, the Advanced Quantum Clock for Real World Applications, is a European consortium of five industry leaders, two national measurement institutes and three universities. The AQuRA clock will be the first industry led clock prototype aiming for instability and uncertainty at around a second over the age of the universe.
Such precise and accurate clocks are crucial for the precise navigation, communications and sensing challenges that underpin our modern society. 
The goal of AQuRA is to make the best clocks in the world robust and compact enough for real world applications. These "optical atomic clocks" are amazingly accurate. If such a clock would have been turned on during the Big Bang, almost fourteen billion years ago, the clock would still be ahead or behind by around a second today!
AQuRA aims to make existing optical clocks smaller and more robust. Currently, these clocks do not look like the clocks in your home – they are complicated machines that fill entire laboratories. AQuRA wants to make these clocks transportable, so that they can be used for measurements in the field and eventually even sent to space using satellites. This could for example make GPS systems much more accurate. AQuRA is one of the quantum technology related projects that together form the European Commission's Quantum Flagship initiative. On this website, you will find our latest news, an overview of the project's tasks, a more detailed description of the twelve partner institutes that make the project possible and open positions. as well as an overview of media appearances and materials.

Recent news10 July 2025: QuRIOUS: a new doctoral programme on optical quantum clocks
The European Commission has decided to fund the doctoral network QuRIOUS – Quantum Research and Innovation in Optical clocks for Upcoming Scientists – which will train and develop the skills of 15 doctoral students on the topic of optical clocks and their applications. The programme will be coordinated by the University of Amsterdam, and involves eleven academic and industrial partners throughout Europe, as well as eleven additional associated partners.
