Nanophotonics offers opportunities for engineering and exploiting the quantum properties of
light by integrating quantum emitters into nanostructures, and offering reliable paths to …

Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

Conventional spectroscopy uses classical light to detect matter properties through the
variation of its response with frequencies or time delays. Quantum light opens up new …

Entanglement is one of the most fascinating properties of quantum mechanical systems;
when two particles are entangled the measurement of the properties of one of the two allows …

Controlling the output of a light emitter is one of the basic tasks in photonics, with landmarks
such as the development of the laser and single-photon sources. The ever growing range of …

Plasmon-enhanced Raman scattering can push single-molecule vibrational spectroscopy
beyond a regime addressable by classical electrodynamics. We employ a quantum …

We demonstrate theoretically the bundle emission of n strongly correlated phonons in an
acoustic cavity QED system. The mechanism relies on Stokes resonances that generate …

The interaction of a resonant light field with a quantum two-level system is of key interest
both for fundamental quantum optics and quantum technological applications employing …

Thermal or chaotic light sources emit radiation characterized by a slightly enhanced
probability of emitting photons in bunches, described by a zero-delay second-order …

Spectral filtering of resonance fluorescence is widely employed to improve single photon
purity and indistinguishability by removing unwanted backgrounds. For filter bandwidths …
