World Quantum Day - April 14 - Events in Austria


The World Quantum Day is an initiative by quantum scientists from around the World on April 14. It is a decentralized and bottom-up initiative, inviting all scientists, engineers, educators, communicators, entrepreneurs, technologists, historians, philosophers, artists, museologists, producers, etc., and their organisations, to develop their own activities, such as outreach talks, exhibitions, lab tours, panel discussions, interviews, artistic creations, etc., to celebrate the World Quantum Day around the world.

Why April 14?

The World Quantum Day is celebrated on April 14, a reference to 4.14, the rounded first digits of Planck’s constant: 4.135667696×10−15 eV.s = 0,000 000 000 000 004 135667696 electronvolt second, a product of energy and time that is the fundamental constant governing quantum physics. Why is Planck’s constant so important? Did you know it is used to define the kilogram? And, otherwise, how does it affect our lives? These are some of the questions, among many others, that will be addressed by the World Quantum Day activities.


The World Quantum Day aims at engaging the general public in the understanding and discussion of Quantum Science and Technology, namely:

  • how it helps us understand nature at its most fundamental level,
  • how it helped us develop technologies that are crucial for our life today,
  • and how it can lead to future scientific and technological revolutions, and how these can impact our society.
