  • In this manuscript, Finco et al demonstrate the use of a quantum magnetometer based on a single NV centre for all-optical imaging of antiferromagnetic (AFM) spin textures. By exploiting variations of the NV spin relaxation rate, they succeed in imaging AFM domain walls and skyrmions.

  • Designing efficient nonlinear dynamic resonances for weak signal amplification remains a challenge. Here, the authors demonstrate a resonance manipulation strategy able to enhance weak signals in a nonlinear oscillator consisting of an optically-probed driven nano-electromechanical resonator.

  • Quantum information science requires a source of entangled photon pairs, but existing sources suffer from a low intrinsic efficiency or poor extraction efficiency. Collecting emitted photons from quantum dots can be improved by coupling the dots to an optical cavity, but this is not easy for entangled photon pairs. Now, a suitable optical cavity has been made in the form of a 'photonic' molecule — two identical, connecting microcavities that are deterministically coupled to the optically active modes of a pre-selected quantum dot.
