• Experimental Setup for RF E-field Strength Measurement using Rydberg Atom-based Quantum Sensor
  (this setup is at NISER, Bhubaneswar; CSIR-NPL and NISER have worked in collaboration for initial set of experimental data)

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.

About the Initiative/Technology: The photocatalysis experiments were performed under two conditions: (i) Under bare sunlight (Intensity ~ 900W/m2) (ii) focussing the sample under the sunlight via converging lens (1800W/m2). The photocatalytic efficiencies were then compared and the best photocatalytic efficiency achieved under sunlight was 98.4% for organic pollutants and 75% for industrial waste via converging lens while the corresponding efficiencies with bare sunlight were 98.1% and 73% respectively. To the best of the author’s knowledge, a rapid and highly efficient photocatalysis of CZTS NPs employing a converging lens for water-remediation without the usage of noble & transition-metals has been reported for the first time
