Abstract:

We demonstrate unprecedentedly long lifetimes for electron spin superposition states of a single trapped 40Ca+ ion. For a Ramsey measurement, we achieve a 1/e coherence time of 300(50) ms, while a spin-echo experiment yields a coherence time of 2.1(1) s. The latter corresponds to residual effective rms magnetic field fluctuations ≤2.7×10-12T during a measurement time of about 1500 s. The suppression of decoherence induced by fluctuating magnetic fields is achieved by combining a two-layer μ-metal shield, which reduces external magnetic noise by 20–30 dB for frequencies of 50 Hz–100 kHz, with Sm2Co17 permanent magnets for generating a quantizing magnetic field of 0.37 mT. Our results extend the coherence time of the simple-to-operate trapped-ion spin qubit to ultralong coherence times which so far have been observed only for magnetic insensitive transitions in atomic qubits with hyperfine structure. © 2016, Springer-Verlag Berlin Heidelberg.
