  bibo_abstract:
  - 'Quantum entanglement has been generated and verified in cold-atom experiments
    and used to make atom-interferometric measurements below the shot-noise limit.
    However, current state-of-the-art cold-atom devices exploit separable (i.e., unentangled)
    atomic states. This perspective piece asks the question: can entanglement usefully
    improve cold-atom sensors, in the sense that it gives new sensing capabilities
    unachievable with current state-of-the-art devices? We briefly review the state-of-the-art
    in precision cold-atom sensing, focusing on clocks and inertial sensors, identifying
    the potential benefits entanglement could bring to these devices, and the challenges
    that need to be overcome to realize these benefits. We survey demonstrated methods
    of generating metrologically useful entanglement in cold-atom systems, note their
    relative strengths and weaknesses, and assess their prospects for near-to-medium
    term quantum-enhanced cold-atom sensing.@eng'
