    "abstract": "We describe a method for precise estimation of the polarization of a\nmesoscopic spin ensemble by using its coupling to a single two-level system.\nOur approach requires a minimal number of measurements on the two-level system\nfor a given measurement precision. We consider the application of this method\nto the case of nuclear spin ensemble defined by a single electron-charged\nquantum dot: we show that decreasing the electron spin dephasing due to nuclei\nand increasing the fidelity of nuclear-spin-based quantum memory could be\nwithin the reach of present day experiments.",
