An Integrated Ultralow Noise Spiral Interferometric Laser
William Loh, David Reens, Dave Kharas +14
Photonic integration offers the potential to bring complex high-performance optical systems to the form factor of a compact semiconductor chip. However, the range of system functio…

Real-time magnetic field noise correction using trapped-ion monitor qubits
Kyle DeBry, Agustin Valdes-Martinez, David Reens +2
We demonstrate a trapped-ion protocol in which a nearby, dedicated "monitor" qubit tracks magnetic-field drifts in real time without interrupting data-qubit operations. Using two $…

Error correction of a logical qubit encoded in a single atomic ion
Kyle DeBry, Nadine Meister, Agustin Valdes Martinez +6
Quantum error correction (QEC) is essential for quantum computers to perform useful algorithms, but large-scale fault-tolerant computation remains out of reach due to demanding req…
