Setting process control chart limits for rounded-off measurements

open access: yesHeliyon, 2023
Measurements can often be imprecise and subjected to rounding-off. Typically, this rounding-off is ignored and assumed to have little to no effect. However, when the measuring scale step is not negligible, it may affect statistical control tools such as ...

Limits on atomic qubit control from laser noise

open access: yesnpj Quantum Information, 2022
Technical noise present in laser systems can limit their ability to perform high fidelity quantum control of atomic qubits. The ultimate fidelity floor for atomic qubits driven with laser radiation is due to spontaneous emission from excited energy ...
