A quantum centenary | Science

In the special issue of *Science* celebrating the centenary of quantum mechanics, authors Sumin Jin, Jelena Stajic, and Eric Hand delve into the profound impact that quantum theory has had on our understanding of the universe. The article reflects on the historical journey of quantum mechanics since its inception in the early 20th century, highlighting key milestones that have shaped modern physics. From Max Planck’s introduction of quantized energy levels to the groundbreaking work of Albert Einstein and Niels Bohr, the development of quantum mechanics has revolutionized not only theoretical physics but also practical applications in technology and materials science.

The authors emphasize that the legacy of quantum mechanics extends far beyond academia; it has laid the groundwork for innovations such as semiconductors, lasers, and quantum computing. For instance, the principles of quantum superposition and entanglement are now being harnessed to create powerful quantum computers that could outperform classical machines in solving complex problems. The article also discusses the ongoing challenges and debates in the field, such as the interpretation of quantum mechanics and the quest for a unified theory that reconciles quantum mechanics with general relativity. As we celebrate this centenary, Jin, Stajic, and Hand encourage readers to appreciate the intricacies of the quantum world and its implications for the future of science and technology.

In conclusion, this special issue serves as both a tribute to the pioneering scientists who laid the foundations of quantum theory and a call to action for the next generation of researchers. By exploring the rich history and future potential of quantum mechanics, the authors inspire a deeper understanding of this complex field, urging readers to engage with the ongoing scientific dialogue that continues to shape our perception of reality. As we stand on the brink of a new era in quantum research, the centenary of quantum mechanics not only marks a significant milestone but also opens the door to exciting possibilities that could redefine our technological landscape in the years to come.
