PT Journal AU Haviland, D TI Superconducting circuits: Quantum phase slips SO Nature Physics JI Nat. Phys. PY 2010 BP 565–566 VL 6 DE fromIPMRAS AB Coulomb interactions can cause a rapid change in the phase of the wavefunction along a very narrow superconducting system. Such a phase slip at the quantum level is now measured in a chain of Josephson junctions. ER
