Nonclassical Multiphoton Plasmonic Sensing
We present a multiphoton quantum sensing protocol using nanoslit plasmonic interferometer, enhancing sensitivity through quantum control of photon fluctuations. Postselecting photons, we greatly improved the sensing signal-to-noise ratio. Our approach enables superior performance in photonic sensing, enhancing the detection of analytes and gases via interferometry.
