The production of pairs of entangled photons simply by focusing a laser beam onto a crystal
with a nonlinear optical response was used to test quantum mechanics and to open new …

The extraordinary sensitivity of plasmonic sensors is well-known in the optics and photonics
community. These sensors exploit simultaneously the enhancement and the localization of …

Quantum entanglement is a phenomenon whereby systems cannot be described
independently of each other, even though they may be separated by an arbitrarily large …

The purpose of quantum technologies is to explore how quantum effects can improve on
existing solutions for the treatment of information. Quantum photonics sensing holds great …

Squeezed light generation has come of age. Significant advances on squeezed light
generation have been made over the last 30 years—from the initial, conceptual experiment …

Optical whispering gallery modes (WGMs) derive their name from a famous acoustic
phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This …

The interest in a system often resides in the interplay among different parameters governing
its evolution. It is thus often required to access many of them at once for a complete …

We investigate the quantum-mechanical noise in spectroscopic experiments on ensembles
of N two-level (or spin-1/2) systems where transitions are detected by measuring changes in …

We investigate the properties of angular-momentum states which yield high sensitivity to
rotation. We discuss the application of these ''squeezed-spin''or correlated-particle states to …

The properties of quantum states have led to the development of new technologies, ranging
from quantum information to quantum metrology,,,,,,,,,,,. A recent field of research to emerge …
