Today is World Quantum Day, a day to celebrate quantum science and technology all over the world. The goal is to show people how much quantum research can change the world. Why the 14th of April? It’s a reference to Planck’s constant (4.14 × 10⁻¹⁵ eV·s), which is an important number in quantum physics. World Quantum Day is extra special this year because it is part of the UN’s International Year of Quantum Science and Technology.
This global campaign shows how quantum technology is quietly changing things for the better in areas like health care, energy, communication, and even finance. World Quantum Day 2025 has gotten a big boost from the International Year of Quantum. It has led to all sorts of events in schools, labs, and businesses to show how quantum works in the real action, think about what’s coming next, and help more people learn about quantum physics.
Around the world, here are some highlights The people behind World Quantum Day have made a list of events happening all over the world. Here are a few that really stand out. In Urbana, Illinois, at the Illinois Quantum Information Science and Technology Center, they are holding public talks, hands-on demonstrations, and family activities. What is the goal? To get people of all ages interested in quantum science. The UKRI’s Engineering and Physical Sciences Research Council has given fellowships to 11 up-and-coming UK researchers to help them move up the career ladder in quantum tech.
In the meantime, London is hosting “Quantum Day Celebration 2025,” which includes interactive exhibits, talks by invited speakers, displays, and even a “Silent Quantum Disco.”
- India: A multi-day event with talks and workshops is going on in Gandhinagar. It shows how India’s role in quantum research is growing and what the country plans to do with quantum technology.
- Austria: Vienna is hosting a Quantum Career Day to help students and young professionals figure out what they want to do with their lives in quantum. There will be networking events and panel discussions with experts from both the academic and business worlds.
- Mexico—In Chihuahua, there is an event called “What Quantum Physics Is and Isn’t” (in Spanish) that aims to clear up common misconceptions and make quantum physics easier for Spanish-speaking communities to understand.
- Thailand: The SEA Quantumathon 2025 x World Quantum Day webinar is hosting a virtual hackathon and talks in Nakhon Ratchasima.
The goal is to get people in the area to work together to solve quantum computing problems. World Quantum Day 2025 shows that more and more people agree: quantum is no longer just for physicists. Quantum computing is getting closer to being a useful tool in the real world. It’s becoming a new pillar of innovation, and businesses are more eager than ever to get on board.
