Timeline of Quantum Evolution Over the Century

In 1900, Max Planck introduced the quantum hypothesis, sparking a scientific revolution that would redefine

physics and technology. Over the past century, Quantum mechanics has evolved from a spooky curiosity to a physical

theory. In 1925, Heisenberg and Dirac introduced the concept of quantum mechanics, establishing the foundations of

quantum theory. Since then, quantum entanglement has become a resource, enabling tasks such as teleportation, quantum

key distribution (QKD), and even the foundational protocols of quantum cryptography. In- dia’s National Quantum Mission

(2023-2031) likewise supports such achievements, with funding, thematic hubs, and strategic coordination to foster

innovation in quantum communication, sensing, computation, and materials science. This essay explores the pivotal

moments, scientists, and innovations that mark this extraordinary journey, highlighting the impact of World War II, first

and second quantum revolutions and forecasting a future governed by quantum technologies.
