Scalable Loading of a Two-Dimensional Trapped-Ion Array
C. D. Bruzewicz, R. McConnell, J. Chiaverini +1
We describe rapid, random-access loading of a two-dimensional (2D) surface-electrode ion-trap array based on two crossed photo-ionization laser beams. With the use of a continuous…
Integrated optical addressing of an ion qubit
Karan K. Mehta, Colin D. Bruzewicz, Robert McConnell +3
The long coherence times and strong Coulomb interactions afforded by trapped ion qubits have enabled realizations of the necessary primitives for quantum information processing (QI…
Entanglement with Negative Wigner Function of Three Thousand Atoms Heralded by One Photon
Robert McConnell, Hao Zhang, Jiazhong Hu +2
Quantum-mechanically correlated (entangled) states of many particles are of interest in quantum information, quantum computing and quantum metrology. Metrologically useful entangle…
Reduction of trapped ion anomalous heating by in situ surface plasma cleaning
Robert McConnell, Colin Bruzewicz, John Chiaverini +1
Anomalous motional heating is a major obstacle to scalable quantum information processing with trapped ions. While the source of this heating is not yet understood, several previou…
