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…

Long-lived metastable-qubit memory
Xiaoyang Shi, Jasmine Sinanan-Singh, Kyle DeBry +3
Coherent storage of quantum information is crucial to many quantum technologies. Long coherence times have been demonstrated in trapped-ion qubits, typically using the hyperfine le…
