Emerging Quantum metamaterials and metasurfaces are an entirely new type of materials enabling quantum computers and sensors

Metamaterials are artificial materials designed to control the electromagnetic properties of a medium. Metasurfaces are the two-dimensional version of metamaterials: extremely thin surfaces made up of numerous subwavelength optical nanoantennas, each designed to serve a specific function upon the interaction with light. The metasurfaces contain regularly spaced nanoparticles that can …
