World Quantum Day

World Quantum Day (WQD) is an international event celebrated on April 14 every year. It aims at promoting the public awareness and understanding of quantum science and quantum technology around the world.

History
World Quantum Day started on 14 April 2021 as an initiative by an international group of scientists. The initiative was joined by engineers, educators, science communicators, organizations and others to celebrate the first World Quantum day on 14 April 2022. April 14 was chosen because "4.14" represents the rounded first 3 digits of Planck’s constant: 4.14×10−15 eV·s.

The US Senate passed a resolution commemorating and supporting World Quantum Day on May 2, 2023.

Events
The first World Quantum Day in 2022 included 200+ events in more than 40 countries across 5 continents, while in 2023 the number of events increased to 400+. World Quantum Day is celebrated on and around April 14, since the events don't necessarily have to be on the exact same date.

The activities included talks, symposiums, panel discussions, laboratory tours, artistic creations, interviews and others.

Organization
The global initiative is supported by the World Quantum Day Coordination Team and representatives from more than 65 countries. Each country has 1 or 2 representatives in the World Quantum Day network.
