Driven Dynamics and Rotary Echo of a Qubit Tunably Coupled to a Harmonic Oscillator

Simon Gustavsson, Jonas Bylander, F. Yan +18 more

We have investigated the driven dynamics of a superconducting flux qubit that is tunably coupled to a microwave resonator. We find that the qubit experiences an oscillating field mediated by off-resonant driving of the resonator, leading to strong modifications of the qubit Rabi frequency. This opens an additional noise channel, and we find that low-frequency noise in the coupling parameter causes a reduction of the coherence time during driven evolution. The noise can be mitigated with the rotary-echo pulse sequence, which, for driven systems, is analogous to the Hahn-echo sequence.

'Rotary' photon echoes

François Rohart, P. Glorieux, B. Macke

By setting on resonance a polar gas at low pressure with an inhomogeneously saturating coherent wave, an oscillating transient nutation is observed, the fast damping of which may be principally related to the electromagnetic field inhomogeneity. The authors report the first experimental evidence of 'rotary' photon echoes allowing a partial restoration of the macroscopic polarisation. These 'rotary' echoes are the electric analogues of Solomon's 'rotary spin echoes' in NMR (1959) and must be carefully distinguished from the usual photon echoes related to the free induction decay (FID). The experiments have been performed in the microwave domain and show a dramatic reduction of the expected echo amplitude due to the molecular motion. Eventual applications, alternative methods of detection and the extension to the optical domain of these 'rotary' echoes are discussed.
