Observation of an anomalous decoherence effect in a quantum bath at room temperature
Observation of an anomalous decoherence effect in a quantum bath at room temperature is a scholarly work, published in 2011 in ''Nature Communications''. The main subjects of the publication include quantum, quantum technology, quantum mechanics, physics, quantum Zeno effect, open quantum system, spin, controllability, decoherence-free subspace, quantum decoherence, condensed matter physics, quantum error correction, nanodiamonds, quantum metrology, Dynamical decoupling, Spins, spin exchange relaxation-free magnetometer, Coherence, Dephasing, Nitrogen-vacancy center, and quantum dissipation. The authors demonstrate that, under dynamical decoupling, the double-transition can have longer coherence time than the single-transition even though the former couples to the nuclear spin bath as twice strongly as the latter does.
