    Quantum Sensing Cutting-Edge Research Among 2024’s Top Innovations

    An approach toward non-destructive sample classification via entangled photons recognized as pioneering work in Prestigious APL Photonics Collection
    Schematic experimental setup: on the left, the photon source, which sends the polarisation-entangled signal-Idler photon pair into the measuring section. The signal photon hits the sample (front) and changes its polarisation state. The changed photon property is transferred by entanglement to the idler photon, whose property can now be determined by polarisation optics (quarter-wave plate QWP, linear polarizer LP). Before the measurement takes place, an long pass filter (LPF) is used to keep out interference signals.
