  • Two-dimensional arrays of trapped ion qubits are attractive platforms for quantum information processing, but rapid reloading remains a challenge. Here the authors use a continuous flux of pre-cooled neutral atoms to achieve fast loading of single ions without affecting the coherence of adjacent qubits.

  • A chip-integrated laser with 7.5 × 10−14 fractional frequency instability is demonstrated by active stabilization to an on-chip 6.1-m-long spiral resonator. By using this laser to interrogate the narrow-linewidth transition of 88Sr+, a clock instability averaging down as \(3.9\times 1{0}^{-14}/\sqrt{\tau }\) is achieved.

  • By using a stimulated Brillouin scattering laser in a strontium-ion optical clock instead of the usual bulk-cavity-stabilized laser, the need for vacuum is removed and resonator volume is substantially reduced.
