Abstract
- Quantum technology has the potential to revolutionize sensors and the Internet of Things (IoT). Efficient and secure data transfer among sensors and IoT devices is a major challenge. To address this, the manuscript presents coherent manipulation of the scattering cross section and its sensitivity based on subluminal propagation and rotary photon drag, using an atomic medium with two levels coupled with a cavity. The group index of the proposed atomic medium is measured in the range of - 0.1 ≤ n g ≤ 150 and group velocity in the range of 2 × 10 6 m / s ≤ v g ≤ ± 2 × 10 9 m/s. The maximum delay time is reported to t g = 0.3 μ s and rotary photon drag to θ d = ± 5 micro radian. This effect of photon drag is used in sensing, energy harvesting, and optical switching in IoT. The scattering cross-section of 0.1 × 10 21 m 2 is reported. The scattering cross-section impacts the efficiency and reliability of quantum-based communication for IoT. The maximum cross-sectional sensitivity is measured to S σ = 0.4 × 10 - 19 m 2 / n r . The cross-sectional sensitivity potentially impacts secure communication and highly precise detection in sensors and IoT. [ABSTRACT FROM AUTHOR]
