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

CM Löschnauer, JM Toba, AC Hughes, SA King… - arxiv preprint arxiv …, 2024 - arxiv.org
The central challenge of quantum computing is implementing high-fidelity quantum gates at
scale. However, many existing approaches to qubit control suffer from a scale-performance …

Physical coherent cancellation of optical addressing crosstalk in a trapped-ion experiment

J Flannery, R Matt, LI Huber, K Wang… - Quantum Science …, 2024 - iopscience.iop.org
We present an experimental investigation of coherent crosstalk cancellation methods for
