Absolute calibration

Definition

Absolute calibration is the process of determining the precise response of a measurement instrument or sensor against a known standard, allowing for accurate quantification of measurements. This technique is crucial in fields such as quantum sensors for dark matter detection, where understanding the instrument's sensitivity and accuracy can lead to significant advancements in detecting elusive particles like weakly interacting massive particles (WIMPs). Proper absolute calibration ensures that any readings from quantum sensors can be trusted and compared reliably across experiments.
