World Quantum Day (WQD) is an international event celebrated on April 14 every year. It aims at promoting the public understanding of quantum science and quantum technology around the world. World Quantum Day started on 14 April 2021 as a 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. More information...
