Overview

• The Royal Swedish Academy of Sciences cited demonstrations of macroscopic quantum tunneling and quantized energy exchange in an electrical circuit.
• Using Josephson-junction superconducting devices, the laureates realized a system that transitions between states like a single quantum particle.
• The committee framed the work as foundational for next‑generation quantum computing, quantum cryptography and quantum sensing.
• The key experiments were performed in 1984–1985 and later informed the development of superconducting qubits and related quantum devices.
• The recipients will share a gold medal, a diploma and 11 million Swedish kronor.
