Optical computing. Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing. For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
e. 5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2] Discs using this technology could be capable of storing up to 360 ...
An optical mouse is a computer mouse which uses a miniature camera and digital image processing to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse and its need for frequent cleaning. The earliest optical mice detected movement on prepared surfaces, however they never gained ...
Linear optical quantum computing or linear optics quantum computation (LOQC), also photonic quantum computing (PQC), is a paradigm of quantum computation, allowing (under certain conditions, described below) universal quantum computation. LOQC uses photons as information carriers, mainly uses linear optical elements, or optical instruments ...
An optical quantum computer with three qubits calculated the energy spectrum of molecular hydrogen to high precision. [154] The first germanium laser advanced the state of optical computers. [155] A single-electron qubit was developed [156] The quantum state in a macroscopic object was reported. [157] A new quantum computer cooling method was ...
At the top right corner is a monocular for assisting the alignment of the two heads. Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar.
Massachusetts Institute of Technology. Steven Todd Kirsch is an American entrepreneur. He has started several companies and was one of two people who independently invented the first version of the optical mouse. Kirsch has been both a philanthropic supporter of medical research, and a promoter of misinformation about COVID-19 vaccines.
