Dual-Platform Precision Measurement of the to -Factor Ratio in
Brian J. McMahon, Vikram S. Sandhu, John M. Gray +5
We report precision measurements of the ratio of Landé factors between the and states of a single trapped ion. The measurements are…
Characterization of Fast Ion Transport via Position-Dependent Optical Deshelving
Craig R. Clark, Creston D. Herold, J. True Merrill +11
Ion transport is an essential operation in some models of quantum information processing, where fast ion shuttling with minimal motional excitation is necessary for efficient, high…
Modelling noise in global Molmer-Sorensen interactions applied to quantum approximate optimization
Phillip C. Lotshaw, Kevin D. Battles, Bryan Gard +3
Many-qubit Mølmer-Sørensen (MS) interactions applied to trapped ions offer unique capabilities for quantum information processing, with applications including quantum simulation an…
Enabling a Programming Environment for an Experimental Ion Trap Quantum Testbed
Austin Adams, Elton Pinto, Jeffrey Young +4
Ion trap quantum hardware promises to provide a computational advantage over classical computing for specific problem spaces while also providing an alternative hardware implementa…
Generating Target Graph Couplings for QAOA from Native Quantum Hardware Couplings
Joel Rajakumar, Jai Moondra, Bryan Gard +2
We present methods for constructing any target coupling graph using limited global controls in an Ising-like quantum spin system. Our approach is motivated by implementing the quan…
Bridging Classical and Quantum with SDP initialized warm-starts for QAOA
Reuben Tate, Majid Farhadi, Creston Herold +2
We study the Quantum Approximate Optimization Algorithm (QAOA) in the context of the Max-Cut problem. Near-term (noisy) quantum devices are only able to (accurately) execute QAOA a…
Testing the Robustness of Robust Phase Estimation
Adam M. Meier, Karl A. Burkhardt, Brian J. McMahon +1
The Robust Phase Estimation (RPE) protocol was designed to be an efficient and robust way to calibrate quantum operations. The robustness of RPE refers to its ability to estimate a…
Transport Implementation of the Bernstein-Vazirani Algorithm with Ion Qubits
Spencer Fallek, Creston Herold, Brian McMahon +3
Using trapped ion quantum bits in a scalable microfabricated surface trap, we perform the Bernstein-Vazirani algorithm. Our architecture relies upon ion transport and can readily b…
Universal Control of Ion Qubits in a Scalable Microfabricated Planar Trap
Creston D. Herold, Spencer D. Fallek, J. True Merrill +4
We demonstrate universal quantum control over chains of ions in a surface-electrode ion trap, including all the fundamental operations necessary to perform algorithms in a one-dime…
