In a groundbreaking achievement, scientists John Clarke, Michel Devoret, and John Martinis were awarded the 2025 Nobel Prize in Physics for their pioneering work on quantum tunneling in superconducting circuits. Their research, initiated in the mid-1980s, demonstrated that quantum mechanical properties could manifest on a macroscopic scale, challenging the traditional view that quantum effects were confined to the microscopic realm. By constructing superconducting electronic circuits, they showcased how electrons could tunnel through barriers, a phenomenon previously observed only at atomic scales. This discovery laid the foundation for the development of quantum technologies such as quantum cryptography, computers, and sensors, which are now integral to various applications in our daily lives. reuters.com
