Efficient Implementation of a Quantum Algorithm with a Trapped Ion Qudit
Xiaoyang Shi, Jasmine Sinanan-Singh, Timothy J. Burke +2
Demonstration of quantum advantage remains challenging due to the increased overhead of controlling large quantum systems. While significant effort has been devoted to qubit-based…
Spontaneous Raman scattering from metastable states of Ba
Timothy J. Burke, Xiaoyang Shi, Jasmine Sinanan-Singh +2
Quantum logic gates performed via two-photon stimulated-Raman transitions in ions and atoms are fundamentally limited by spontaneous scattering errors. Recent theoretical treatment…
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…
