Fast, high-fidelity addressed single-qubit gates using efficient composite pulse sequences

AD Leu, MF Gely, MA Weber, MC Smith… - Physical Review Letters, 2023 - APS
We use electronic microwave control methods to implement addressed single-qubit gates
with high speed and fidelity, for Ca+ 43 hyperfine “atomic clock” qubits in a cryogenic (100 …

Scalable, high-fidelity all-electronic control of trapped-ion qubits

Coherent control of trapped-ion qubits with localized electric fields

R Srinivas, CM Löschnauer, M Malinowski… - Physical review …, 2023 - APS
We present a new method for coherent control of trapped ion qubits in separate interaction
regions of a multizone trap by simultaneously applying an electric field and a spin …

Dressing trapped ions with integrated wires

RT Sutherland - Physical Review A, 2024 - APS
We discuss dressing trapped ions with the near field of a trap integrated wire. Ram** a
dressing field on or off adiabatically before or after an operation changes its effective …

Focusing of quantum gate interactions using dynamical decoupling

MC Smith, AD Leu, MF Gely, DM Lucas - arxiv preprint arxiv:2309.02125, 2023 - arxiv.org
In 1995, Cirac and Zoller proposed the first concrete implementation of a small-scale
quantum computer, using laser beams focused to micron spot sizes to address individual …

Passive dynamical decoupling of trapped-ion qubits and qudits

RT Sutherland, SD Erickson - Physical Review A, 2024 - APS
We propose a method to dynamically decouple every magnetically sensitive hyperfine
sublevel of a trapped ion from magnetic field noise, simultaneously using integrated circuits …
