Metasurfaces consisting of nanoscale structures are underpinning new physical principles
for the creation and sha** of quantum states of light. Multiphoton states that are entangled …

In 1935, Einstein, Podolsky, and Rosen (EPR) conceived a gedanken experiment which
became a cornerstone of quantum technology and still challenges our understanding of …

High-harmonic generation is a light up-conversion process occurring in a strong laser field,
leading to coherent bursts of extreme ultrashort broadband radiation [Lewenstein et al …

We have modulated the density of a trapped Bose-Einstein condensate by changing the trap
stiffness, thereby modulating the speed of sound. We observe the creation of correlated …

Compared to light interferometers, the flux in cold-atom interferometers is low and the
associated shot noise is large. Sensitivities beyond these limitations require the preparation …

Bell correlations are a foundational demonstration of how quantum entanglement
contradicts the classical notion of local realism. Rigorous validation of quantum nonlocality …

Methods for modeling large driven-dissipative quantum systems are becoming increasingly
urgent due to recent experimental progress in a number of photonic platforms. We …

We study the quantum entanglement of the quasiparticle pairs emitted by analog black
holes. We use a phenomenological description of the spectra in dispersive media to study …

In quantum many-body theory, all physical observables are described in terms of correlation
functions between particle creation or annihilation operators. Measurement of such …

There is an analogy between the propagation of fields on a curved spacetime and shallow
water waves in an open channel flow. By placing a streamlined obstacle into an open …
