Entangled light–matter interactions and spectroscopy

“…The primary questions can be summarized as: 1) How do intermediate states control the entangled photon interaction, 2) what structural motifs can increase or decrease the strength of the entangled photon interaction, 3), how does excited state coupling with spins, vibrations, and electrons preserve or decrease the entangled light-matter interactions, and 4), more generally, how to utilize entanglement to reveal and engineer novel materials and device responses that are not accessible with traditional methods. Other open questions, such as how selection rules are modified by polarization entangled photons and how photonic enhancement techniques will modify the interactions [94][95][96][97][98][99][100][101][102] , promise for intriguing expansions to existing fields.…”

Entangled twophoton processes can occur at the same rate as a pulsed-laserinduced two-photon excitations but at over a million times lower fluxes, accounting for the intensity scaling between quadratic and linear processes.…”

Quantum-Enhanced Plasmonic Sensing

“…While there have been proof-of-principle experimental and theoretical studies of quantum-enhanced plasmonic sensors [20][21][22][23][24], the results presented here represent the first implementation of such a sensor with sensitivity of the same order of magnitude as the classical state-of-the-art. In particular, we detect changes in refractive index of air induced by ultrasonic waves.…”

“…This coherent conversion between photons and plasmons gives rise to a transmission through the sub-wavelength holes orders of magnitude greater than transmissions expected from diffraction theory, an effect known as extraordinary optical transmission (EOT) [25,26]. This process preserves the quantum properties of the light [27][28][29][30] and makes the use of quantum states of light a viable option to enhance the sensitivity of plasmonic sensors [23,24].…”

Multichannel Fiber Optic SPR Sensors: Realization Methods, Application Status, and Future Prospects

“…[225] For this reason, fiber optic sensors based on quantum plasmon show enormous potential for vulnerable and low-concentration analyte detection, such as early cancer cell screening. [226] In addition, the introduction of other quantum states of light, such as entangled states and squeezed states, [227] into the development of MC-SPR sensors is expected to make fiber optic SPR sensors possess the superiorities of multiple channels, high sensitivity, and high precision simultaneously, which has a more attractive prospect.…”
