  • Precise gravity sensing in dynamic environments is challenging. Here, the long-term stability of a matter-wave gravimeter and high bandwidth of an optical resonator are combined in a compact gravity sensor with high seismic noise suppression.

  • Noise is a fundamental obstacle to the stability of atomic optical clocks. An experiment now realizes the design of a spin-squeezed clock that improves interrogation times and enables direct comparisons of performance between different clocks.

  • Matter-wave interferometers provide an opportunity to measure whether quantum superpositions exist at macroscopic length scales or only at microscopically small scales; now such instruments have demonstrated quantum interference of wave packets separated by 54 cm.

  • Inertial sensors using atom interferometry have applications in geophysics, navigation- and space-based tests of fundamental physics. Here, the first operation of an atom accelerometer during parabolic flights is reported, demonstrating high-resolution measurements at both 1g and 0g.

  • Determination of the gravitational constant G using laser-cooled atoms and quantum interferometry, a technique that gives new insight into the systematic errors that have proved elusive in previous experiments, yields a value that has a relative uncertainty of 150 parts per million and which differs from the current recommended value by 1.5 combined standard deviations.

  • Ghost imaging is demonstrated using beams of correlated pairs of ultracold helium atoms, rather than photons, yielding a reconstructed image with submillimetre resolution.
