PT Journal AU Lupascu, A TI Nonlinear dynamics: Quantum pendula locked in SO Nature Physics JI Nat. Phys. PY 2011 BP 100 EP 101 VL 7 IS 2 DE fromIPMRAS AB A study of the autoresonant behaviour of a superconducting pendulum reveals that quantum fluctuations determine only the initial oscillator motion and not its subsequent dynamics. This could be important in the development of more efficient methods for reading solid-state qubits. ER
