Today, April 14th,, the global scientific community will come together to celebrate World Quantum Day, marking 100 years since the inception of quantum mechanics. This day not only honors the profound impact of quantum science on our understanding of the universe but also highlights its transformative applications in modern technology.

The choice of April 14 (4.14) is symbolic, representing the first three digits of Planck's constant (4.1356677×10⁻¹⁵ eV·s), a fundamental constant in quantum physics. This constant underscores the quantization of energy levels, a cornerstone concept introduced by Max Planck in 1900, which laid the foundation for quantum theory.

A Century of Quantum Mechanics

The year 2025 holds special significance as it commemorates a century since the formal establishment of quantum mechanics. Over the past 100 years, quantum science has revolutionised our understanding of matter and energy at the most fundamental levels. From the early theoretical frameworks to groundbreaking experiments, quantum mechanics has paved the way for numerous technological advancements that permeate our daily lives.

In recognition of this milestone, various events are scheduled worldwide, you can find all the event here: https://worldquantumday.org/upcoming-events

As we celebrate World Quantum Day 2025, we not only reflect on a century of scientific achievements but also look forward to the future possibilities that quantum technologies promise. From quantum computing to secure communication, the advancements in this field hold the potential to revolutionise various sectors, including healthcare, finance, and cybersecurity. Engaging with these developments ensures that societies worldwide can harness the benefits of quantum innovations responsibly and equitably.
