(Nanowerk News) Metasurfaces, composed of nanoresonator arrays with tailored structure and subwavelength feature size, show the potential of manipulating various degrees of freedom for manipulating ...

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate. As the demand for digital security grows ...

(Nanowerk Spotlight) Light passing through most transparent materials, like glass lenses or windows, behaves the same way regardless of which direction it travels. This property, known as Lorentz ...

Engineers are introducing the first all-optical "stealth" encryption technology that will be significantly more secure and private for highly sensitive cloud-computing and data center network ...

Privacy is an obvious concern now that everything from smartphones to smartwatches to even smart glasses has built-in cameras. Banning covert cameras is never going ...

The coordinator of the European Commission-supported "CiViQ" project - part of the wider billion-euro flagship effort to develop useful quantum technologies - says that new prototypes will be tested ...
