DOI: 10.1038/s41467-024-47294-5 It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes through the material. This property is utilized in […]
Credit: CC0 Public Domain Quantum technology is based on the engineering of devices that make use of the quantum properties of matter. One of the most prominent avenues of this technology is quantum computing, which may be able to leverage quantum bits (qubits) to perform calculations more efficiently than classical computers. Technology with this “quantum […]

Credit: Light: Science & Applications (2024). DOI: 10.1038/s41377-024-01376-7 In recent years, artificial intelligence technologies, especially machine learning algorithms, have made great strides. These technologies have enabled unprecedented efficiency in tasks such as image recognition, natural language generation and processing, and object detection, but such outstanding functionality requires substantial computational power as a foundation. Current computational […]
Researchers developed a 3D full-color display method that uses a smartphone screen, rather than a laser, to create holographic images. Shown are their experimental results, in which a continuous transition from the first layer to the second layer is observable.
