A Classically Efficient Quantum Scalable Fermi-Hubbard Benchmark
Bryan T. Gard, Adam M. Meier
In order to quantify the relative performance of different testbed quantum computing devices, it is useful to benchmark them using a common protocol. While some benchmarks rely on…
High-Fidelity Bell-State Preparation with Ca Optical Qubits
Craig R. Clark, Holly N. Tinkey, Brian C. Sawyer +10
Entanglement generation in trapped-ion systems has relied thus far on two distinct but related geometric phase gate techniques: Molmer-Sorensen and light-shift gates. We recently p…
Quantum process tomography of a Mølmer-Sørensen gate via a global beam
Holly N Tinkey, Adam M Meier, Craig R Clark +2
We present a framework for quantum process tomography of two-ion interactions that leverages modulations of the trapping potential and composite pulses from a global laser beam to…
Single-ion addressing via trap potential modulation in global optical fields
Christopher M. Seck, Adam M. Meier, J. True Merrill +4
To date, individual addressing of ion qubits has relied primarily on local Rabi or transition frequency differences between ions created via electromagnetic field spatial gradients…
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…
Randomized Benchmarking of Clifford Operators
Adam M. Meier
Randomized benchmarking is an experimental procedure intended to demonstrate control of quantum systems. The procedure extracts the average error introduced by a set of control ope…
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…
Magic-state distillation with the four-qubit code
Adam M. Meier, Bryan Eastin, Emanuel Knill
The distillation of magic states is an often-cited technique for enabling universal quantum computing once the error probability for a special subset of gates has been made negligi…
Randomized Benchmarking of Multi-Qubit Gates
J. P. Gaebler, A. M. Meier, T. R. Tan +8
As experimental platforms for quantum information processing continue to mature, characterization of the quality of unitary gates that can be applied to their quantum bits (qubits)…
Single-qubit-gate error below 10^-4 in a trapped ion
K. R. Brown, A. C. Wilson, Y. Colombe +5
With a 9Be+ trapped-ion hyperfine-states qubit, we demonstrate an error probability per randomized single-qubit gate of 2.0(2) x 10^-5, below the threshold estimate of 10^-4 common…
