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…

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…

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…
