experimental_setup_for_RF_E-field_strength_measurement_using_Rydberg_atom-based_quantum_sensor

Introduction: Rydberg Atom based Quantum-Sensor for E-Field Sensing

About the Initiative/Technology: The atom-based standards have been accepted worldwide for measurement of time, frequency, gravity, magnetometry, and length. To date, the RF E-field sensing and calibration techniques does not have traceability to physical constants and have complex traceability path. The dependency on the materials under use, limitation of bandwidth of antennae under use, the surrounding parameters at the time of measurement, and the incorrect evaluation of uncertainties are some of the limitations of current techniques which makes measurable quantity vulnerable to the errors. These measurements will lead to establish the quantum communication and quantum sensing calibration facilities at CSIR –NPL for upcoming smart communication devices.
