Controlling light while measuring trapped ion qubits

AQM characterization scheme. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-50864-2 Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for performing controlled quantum operations, especially when protocols such as quantum error correction involve measurements or resets that corrupt the state of neighboring qubits. Current methods for protecting atomic qubits from disturbances waste…
