The Quantum Leap: From Theory to Practice

The trio's research, conducted in 1985 at the University of California, Berkeley, focused on the behavior of charged particles in superconducting circuits called Josephson junctions. Their experiments revealed that these particles exhibited distinct quantum properties, including energy quantization and quantum tunneling, even in macroscopic systems 1
