  2. Optical computing - Wikipedia

    en.wikipedia.org/wiki/Optical_computing

    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).

  3. Optical storage - Wikipedia

    en.wikipedia.org/wiki/Optical_storage

    Optical storage is the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning optical disc. An older example of optical storage that does not require the use of computers, is microform.

  4. Linear optical quantum computing - Wikipedia

    en.wikipedia.org/wiki/Linear_optical_quantum...

    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 ...

    Optical drives let your computer read and interact with discs like CDs, DVDs, and Blu-rays. However, they're quickly becoming outdated.

  6. Magneto-optical drive - Wikipedia

    en.wikipedia.org/wiki/Magneto-optical_drive

    A magneto-optical drive is a kind of optical disc drive capable of writing and rewriting data upon a magneto-optical disc. 130 mm (5.25 in) and 90 mm (3.5 in) discs were the most common sizes. In 1983, just a year after the introduction of the compact disc, Kees Schouhamer Immink and Joseph Braat presented the first experiments with erasable ...

  7. Optical disc drive - Wikipedia

    en.wikipedia.org/wiki/Optical_disc_drive

    Optical disc drive. In computing, an optical disc drive (ODD) is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, while other drives can both read and record.

    en.wikipedia.org/wiki/5D_optical_data_storage

    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 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 ...
