Quantum 1.0 to 2.0: Building the Future on a Century of Discovery  By Ortwin Hess About a century ago, the emergence of quantum mechanics—Quantum 1.0—revolutionized our understanding of nature at its most fundamental level, unlocking the mysteries of atomic structure, superconductivity, and quantum optics. This first quantum revolution laid the foundation for much of today's technology, from semiconductors and lasers to nuclear magnetic resonance. Now, with the advent of Quantum 2.0, we are not merely applying quantum principles but actively harnessing quantum superposition, entanglement, and coherence to create transformative technologies. Quantum computers, ultra-secure quantum communication, and quantum-enhanced sensing hold the potential to reshape industries, from healthcare and materials science to artificial intelligence and cybersecurity. Yet, while these breakthroughs inspire excitement, it is crucial to recognize that both quantum revolutions demand continued fundamental research. The realization of practical quantum technologies depends not only on advances in quantum information science and quantum algorithmics but also on their successful implementation in physical platforms that leverage genuine quantum properties. Bridging the gap between abstract quantum models and real-world quantum devices—whether in superconducting circuits, trapped ions, nanophotonic systems, or emerging solid-state architectures—remains one of the defining challenges of our time. It is precisely this vital connection between theory and experiment, between information and implementation, that is at the heart of APL Quantum.   To transition from proof-of-concept demonstrations to scalable, robust, widely deployable and sustainable quantum technologies, we must foster deep collaborations between physicists, computer scientists, engineers, and material scientists. This requires not only scientific ingenuity but also a commitment to international cooperation, open-access knowledge, and interdisciplinary engagement. Through initiatives like the International Year of Quantum and publishing platforms such as APL Quantum, we have a unique opportunity to catalise discovery, support researchers worldwide, and inspire a new generation to contribute to the quantum revolution—one that continues to unfold before us. Ortwin Hess, Trinity College Dublin APL Quantum, Editor-in-Chief Quantum Science: Unlocking the Future, Together   By Philippe Bouyer Quantum science is transforming technology, promising breakthroughs like ultra-sensitive sensors for early medical diagnosis, better prediction of natural disasters, and ultra-secure communication. Quantum technologies could also power faster, energy-efficient computers, driving advances in medicine, energy, and environmental protection.   Yet, quantum technology is still emerging and requires global collaboration from experts worldwide. Enhancing public understanding is equally important, as quantum concepts often seem complex or mysterious. Demystifying quantum science builds trust, inspires curiosity, and encourages future innovators.     By working together and fostering open discussions, we can unlock quantum's potential to solve great mysteries such as dark matter, advance biological research, and improve medicines, materials, and sustainability—creating a brighter future for everyone.   Philippe Bouyer University of Amsterdam   AVS Quantum Science, Editor-in-Chief Open Access, Global Impact: Supporting the Quantum Frontier By Penelope A. Lewis Quantum science is a field at the very forefront of technological innovation — a field uniquely situated to deliver transformative breakthroughs that will shape the future. From ultra-sensitive sensors and communication security to energy-efficient computing, the potential of these technologies is enormous and profound. At AIP Publishing, we're committed to supporting the global research community behind the advance of these emerging technologies. By fostering open access to the latest groundbreaking research, we're empowering investigators worldwide to unlock quantum science's full potential. Together, we can push this field to new heights, inspire curiosity, and drive innovation that will serve and benefit the world for generations to come. On World Quantum Day, as we celebrate the International Year of Quantum Science and Technology, we're reflecting on our role in that journey and looking with anticipation toward a hopeful future.
