Press Release Improving The Lifetime Of An Electron Spin In Diamond (1) mechanism to improve the lifetime of the electron spin in diamond via a coupling with the superconducting flux qubit (fig.3) fig.3 mechanism to improve the coherence time of the nv center a defect that consists of a nitrogen atom and a vacancy in diamond lattice is called a nitrogen vacancy (nv) center, which has single electron spins (fig.1). The nv centre in diamond has been used extensively in quantum information processing; however fault tolerant readout of its spin remains challenging. here, zhang et al demonstrate a robust scheme.
Improving The Lifetime Of An Electron Spin In Diamond For Quantum Nitrogen vacancy (nv) centers in diamond (fig. 1a) are a particularly promising platform for such spin based quantum sensing applications, because they host a single electron spin 10 with long. The principle is that the π pulse in the middle flips electron spin, making the phase noises accumulated during the first and second evolution time cancel each other for one dimension. for nv spin system, nv electron spin evolutes under the environment of nuclear spin bath of c 13 spin 1 2. the evolution goes under two conditions: 1. In solid state spin systems, relaxation into the phonon bath usually dominates over the coupling to the electromagnetic vacuum1–9. in the quantum limit, the spin lifetime is determined by. Spin sublevels that are more sensitive to magnetic elds [9, 10]. moreover, all optical manipulation techniques are important for the development of integrated nanopho tonic systems for diamond based scalable quantum op tical devices and quantum networks [11{13]. in these devices, microwave structures on the diamond substrate.

N recent years, solid state electron spin in diamonds has become increasingly significant in quantum science and sensing experiments.1–3) the nitrogen vacancy (nv) color center (nv negative charge) has two essential features, which are a long coherence time at room temperature,4–6) and an all optical initialization and readout7,8) of nv. In the study, the authors specifically use the electron spin of an nv center coupled to the nuclear spin of a proximal 13 c. the 13 c nuclear spin (or ) is used to encode the vectors, while the nv electron spin qutrit (, , ) is used as the ancilla to perform the projection measurement and readout (figure 2(c)).
