Quantum information technology based on solid state qubits has created much interest in
converting quantum states from the microwave to the optical domain. Optical photons, unlike …

Quantum memory is essential for the development of many devices in quantum information
processing, including a synchronization tool that matches various processes within a …

This tutorial introduces the theoretical and experimental basics of electromagnetically
induced transparency (EIT) in thermal alkali vapors. We first give a brief phenomenological …

Metasurfaces characterized by a transverse gradient of local impedance have recently
opened exciting directions for light manipulation at the subwavelength scale. Here we add a …

Coherent preparation by laser light of quantum states of atoms and molecules can lead to
quantum interference in the amplitudes of optical transitions. In this way the optical …

A plasmonic “molecule” consisting of a radiative element coupled with a subradiant (dark)
element is theoretically investigated. The plasmonic molecule shows electromagnetic …

Electromagnetically induced transparency,, is a quantum interference effect that permits the
propagation of light through an otherwise opaque atomic medium; a 'coupling'laser is used …

Analogue gravity is a research programme which investigates analogues of general
relativistic gravitational fields within other physical systems, typically but not exclusively …

We identify form-stable coupled excitations of light and matter (“dark-state polaritons”)
associated with the propagation of quantum fields in electromagnetically induced …

We report an experiment in which a light pulse is effectively decelerated and trapped in a
vapor of Rb atoms, stored for a controlled period of time, and then released on demand. We …
