Summary
We developed a new method to observe quantum coherence in surface plasmon polaritons, confirming wave-particle duality for these light-matter interactions.
Area of Science:
- Quantum Optics
- Condensed Matter Physics
- Nanophotonics
Background:
- Nitrogen vacancy color centers are quantum emitters.
- Surface plasmon polaritons (SPPs) are light-matter quasiparticles confined to surfaces.

Purpose of the Study:
- To present an experimental methodology for observing spatio-temporal second-order quantum coherence of SPPs.
- To investigate the quantum nature of SPPs emitted by nitrogen vacancy color centers.
- To test the wave-particle duality of SPPs using the developed technique.
Main Methods:
- Utilized leakage radiation microscopy in Fourier space.
- Employed nitrogen vacancy color centers at the apex of an optical tip as SPP sources.
- Performed measurements to characterize spatio-temporal coherence properties.
Main Results:
- Successfully observed spatio-temporal second-order quantum coherence of SPPs.
- Demonstrated the capability of the method to probe quantum phenomena.
- Provided experimental evidence for wave-particle duality of SPPs.
Conclusions:
- The developed methodology enables the study of quantum coherence in SPPs.
- Nitrogen vacancy color centers are viable sources for quantum SPP experiments.
- The findings support the wave-particle duality of surface plasmon polaritons, advancing quantum optics research.
