Remote entanglement need not be the bottleneck for modular trapped-ion quantum computing
Felix W. Knollmann, David P. Nadlinger, John Blue +7
Modularity underpins classical computing; as quantum processors encounter limits on fabrication yield, reliability, and size, they will also need it acutely. The bottleneck to link…
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 $…
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.…
Integrated-Photonics-Based Systems for Polarization-Gradient Cooling of Trapped Ions
Sabrina M. Corsetti, Ashton Hattori, Ethan R. Clements +14
Trapped ions are a promising modality for quantum systems, with demonstrated utility as the basis for quantum processors and optical clocks. However, traditional trapped-ion system…
