Quantum Physics
Without quantum mechanics, many of the technologies we rely on today would be almost unimaginable. Computers and smartphones as we know them would not exist – nor would lasers or LEDs. We would also lack crucial tools for developing new materials and medicines. Groundbreaking fields such as quantum cryptography and quantum computing – now at the forefront of research in institutions and companies worldwide – would be inconceivable. Yet beyond these practical applications, our understanding of the universe would be missing a fascinating dimension: the profound insights into the microscopic world that quantum physics offers. This is why so many researchers at the Max Planck Institutes dedicate their work to this field. They are not only laying the groundwork for future technological breakthroughs – particularly in quantum information science – but also continuing to uncover surprising truths about the nature of reality at its most fundamental level.
