On Friday, India joined 65 countries in celebrating the 2nd World Quantum Day. Since 2021, April 14 has been marked as World Quantum Day globally in order to observe the research efforts utilizing quantum technologies. World Quantum Network chose April 14 to promote public awareness of Quantum Science and Technology.

April 14 is a reference to 4.14, the rounded first digits of Planck's constant- 4.135667696×10-15 eV/Hz, a product of energy & time that is the fundamental consistent governing quantum physics. This network comprises scientist representatives from around 65 nations. Professor Urbasi Sinha from the Raman Research Institute, Bengaluru, and Professor Arun K. Pati, Head of Centre for Quantum Science & Technology, International Institute of Information Technology Hyderabad (IIITH), are representing India.

Professor Urbasi Sinha, Group Head of the Quantum Information and Computing (QuIC) lab at RRI, said it is lovely to have a day in the year devoted to honoring all things quantum. Raman Research Institute has been at the vanguard of quantum technology research in the nation. I am excited at the opportunities in this area for Indian researchers. Sharing his thoughts on quantum technologies, Professor Arun K. Pati said, Quantum Mechanics supervises all the happenings in the universe.

More so, quantum mechanics has delivered a climb to revolutionary domains of Quantum Computing, Quantum Communication, and Quantum Technology– all of which will have a huge contribution to society" This year's World Quantum Day observed the Nobel Prize in Physics (2022) which was rewarded to the trio Alain Aspect, John F. Clauser, and Anton Zeilinger for their actions and experimentations with entangled photons, demonstrating the breach of Bell inequalities and pioneering quantum information science. India organised online and physical events to mark this day.

Around the world, around 350 events were scheduled to observe on this day.
