  • The standard quantum limit bounds the precision of quantum measurements. Now, a protocol based on time-reversal operations with cold atoms overcomes that limit and achieves the greatest phase sensitivity improvement in any full Ramsey interferometer.

  • This work shows how to connect a fibre to a single-photon source based on quantum dots in microcavities. The alignment relies on reflectivity measurements. The structure is stable from room to cryogenic temperature and over several cooling cycles.

  • Here, dynamical light squeezing is observed in the emission from two coupled weakly nonlinear populations of exciton-polaritons through ultrafast time-resolved second-order correlation measurements. Full quantum simulations link the squeezing to the periodic bunching observed in the light statistics.

  • A many-atom state of trapped 171Yb atoms that are entangled on an optical atomic-clock transition overcomes the standard quantum limit, providing a proof-of-principle demonstration towards entanglement-based optical atomic clocks.
