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 $…
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…
Collection of fluorescence from an ion using trap-integrated photonics
Felix W. Knollmann, Sabrina M. Corsetti, Ethan R. Clements +12
Spontaneously emitted photons are entangled with the electronic and nuclear degrees of freedom of the emitting atom, so interference and measurement of these photons can entangle s…
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…
Sub-Doppler cooling of a trapped ion in a phase-stable polarization gradient
Ethan Clements, Felix W. Knollmann, Sabrina Corsetti +17
Trapped ions provide a highly controlled platform for quantum sensors, clocks, simulators, and computers, all of which depend on cooling ions close to their motional ground state.…
