Summary
We coupled squeezed light to silver nanostructures, demonstrating the transfer of quantum correlations. This breakthrough enables parallel quantum information processing on subwavelength scales.
Area of Science:
- Quantum optics
- Plasmonics
- Nanophotonics
Background:
- Macroscopic quantum correlations, such as squeezed light, are crucial for advanced quantum technologies.
- Localized surface plasmons (LSPs) offer unique light-matter interaction properties at the nanoscale.
Purpose of the Study:
- To demonstrate the transduction of macroscopic quantum correlations using LSPs.
- To explore the potential of LSP-mediated coupling for on-chip quantum information processing.
Main Methods:
- Generated squeezed light via four-wave mixing in Rb vapor.
- Coupled the squeezed light to a silver nanohole array exhibiting LSP-mediated extraordinary optical transmission.
- Utilized a 795 nm spectral overlap between the squeezed light and the LSP resonance.
Main Results:
- Successfully coupled quantum light (squeezed light) into LSPs.
- Demonstrated the conservation of spatially dependent quantum information during transduction.
- Achieved the first experimental coupling of quantum light into LSPs.
Conclusions:
- LSP-mediated coupling can effectively transduce macroscopic quantum correlations.
- This technique enables parallel quantum protocols for subwavelength quantum information processing.
- Opens new avenues for integrated quantum photonic circuits.
