    Summary

    We developed a compact squeezed-light magnetometer using four-wave mixing in rubidium vapor. This method achieves 4.7 dB quantum noise reduction for enhanced magnetometry measurements.

    Area of Science:

    • Atomic, Molecular, and Optical Physics
    • Quantum Optics
    • Magnetometry

    Background:

    • Squeezed-light magnetometry offers enhanced sensitivity beyond the standard quantum limit.
    • Nonlinear magneto-optical rotation (NMOR) is a sensitive probe of magnetic fields in atomic vapors.

    Purpose of the Study:

    • To demonstrate a compact and accessible squeezed-light magnetometer.
    • To leverage four-wave mixing in rubidium vapor for enhanced NMOR signals.

    Main Methods:

    • Utilized four-wave mixing in a single hot rubidium vapor cell to generate a two-mode relative-intensity squeezed state.
    • Applied nonlinear magneto-optical rotation (NMOR) to each mode of the squeezed state.
    • Combined polarization rotation signals from probe and conjugate fields.
