Midcircuit Operations Using the <i>omg</i> Architecture in Neutral Atom Arrays Open
Midcircuit operations, such as qubit state measurement or reset, are central to many tasks in quantum information science, including quantum computing, entanglement generation, and metrology. For instance, in quantum error correction, the …

Mid-circuit operations using the omg-architecture in neutral atom arrays Open
We implement mid-circuit operations in a 48-site array of neutral atoms, enabled by new methods for control of the $\textit{omg}$ (optical-metastable-ground state qubit) architecture present in ${}^{171}$Yb. We demonstrate laser-based cont…

Correlated photon-pair generation in a liquid-filled microcavity Open
We report on the realization of a liquid-filled optical microcavity and demonstrate photon-pair generation by spontaneous four-wave mixing. Our source has a spectral brightness of 45 ± 7 mW −2 s −1 MHz −1 and the bandwidth of the emitted p…

Correlated photon-pair generation in a liquid-filled microcavity Open
We report on the realization of a liquid-filled optical microcavity and demonstrate photon-pair generation by spontaneous four-wave mixing. The bandwidth of the emitted photons is $\sim 300$ MHz and we demonstrate tuning of the emission wa…
