Superradiance, characterized by the collective, coherent emission of light from an excited
ensemble of emitters, generates photonic signals on timescales faster than the natural …

Single-photon entanglement is one of the primary resources for quantum networks,
including quantum repeater architectures. Such entanglement can be revealed with only …

Metamaterials are artificially engineered periodic structures with exceptional optical
properties that are not found in conventional materials. However, this definition of …
