Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study led by ...
The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a Berlin team led by theoretical physicist Prof. Dr. Jens Eisert of Freie Universität Berlin and HZB has shown that ...
Metal halide perovskites have become well-deserved "star" materials among a variety of semiconductors owing to their excellent optoelectronic properties, such as high photoluminescence (PL) quantum yield (QY), high absorption ...
Smart materials that can rapidly respond to external stimuli possess immense potential for applications in anti-counterfeiting and encryption, data storage, sensors, bioimaging, and so on. However, most stimulus-responsive ...
Researchers have made a significant breakthrough in controlling the polarization of light, a crucial property for various applications such as augmented reality, data storage, and encryption.
Credit cards embedded chips, national mints printed watermarks, and high-profile locations installed retina scanners all for the same reason—to protect information. As attackers grow smarter, so must defense.
National University of Singapore (NUS) physicists have developed a method of converting fish scale waste into a versatile material with dual functionalities—encryption of sensitive information and acting as a bio-adsorbent ...
Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows holograms to display multiple ...
Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator—a specific type of quantum computer—could ...
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted ...
