TL;DR: A comparison of the neutron scattering length of carbon evaluated from a high precision total cross section measurement and the scattering length as measured with the neutron gravity refractometer leads to the most accurate determination of the equivalence factor γ between the gravitational and inertial mass for the neutron γ = 100038∓000025 as mentioned in this paper.

TL;DR: In this paper, the authors proposed a method to maximize the fidelity of quantum memory implemented by a spectrally inhomogeneous spin ensemble by preselecting the optimal spectral portion of the ensemble by judiciously designed pulses.

TL;DR: A scalable protocol is proposed, which significantly reduces the constraints on the emitter and greatly widens the set of physical systems suited for scalable entangled-photon generation and enables performance enhancement of existing platforms.

TL;DR: The experimental demonstration of quantum memory for collective atomic states in a far-detuned optical dipole trap that probes the quantum storage by cross correlation of the photon pair arising from the Raman scattering and the retrieval of the atomic state stored in the memory.

TL;DR: In this paper, the authors studied the complex quantum dynamics of a system of many interacting atoms in an elongated anharmonic trap, and the experimental realization of this system displays decaying oscillations of the atomic density distribution.
