TL;DR: It is shown that QBA on a macroscopic mechanical oscillator can be evaded if the measurement of motion is conducted in the reference frame of an atomic spin oscillator, and this hybrid quantum system paves the way to entanglement generation and distant quantum communication between mechanical and spin systems and to sensing of force, motion and gravity beyond the standard quantum limit.

TL;DR: The first detection of action potentials from an animal nerve using an optical atomic magnetometer is presented, able to achieve the sensitivity dominated by the quantum shot noise of light and quantum projection noise of atomic spins.

TL;DR: In this article, the authors demonstrate the generation of an entangled state between the motion of a macroscopic mechanical oscillator and a collective atomic spin oscillator, as witnessed by an Einstein-Podolsky-Rosen variance below the separability limit.

TL;DR: In this paper, the first detection of action potentials from an animal nerve using an optical atomic magnetometer was presented, using an optimal design to achieve the sensitivity dominated by the quantum shot noise of light and quantum projection noise of atomic spins.

TL;DR: In this article, an entangled state between the motion of a macroscopic mechanical oscillator and a collective atomic spin oscillator, as witnessed by an Einstein-Podolsky-Rosen variance below the separability limit, 0.83 ± 0.02 < 1.
