Adaptive Measurements

Definition

Adaptive measurements refer to a strategy in quantum sensing where the measurement process is dynamically adjusted based on the results obtained during the measurement itself. This approach allows for enhanced sensitivity and accuracy by optimizing measurement parameters in real-time, which is particularly valuable in complex biological systems where conditions can change unpredictably. By adapting the measurement process, quantum sensors can extract more information from the system being studied, improving their overall performance.
