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).
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]
Jiuzhang (Chinese: 九章) is the first photonic quantum computer to claim quantum supremacy.Previously quantum supremacy has been achieved only once in 2019 by Google's Sycamore, however Google's computer was based on superconducting materials, and not photons.

An older example of optical storage that does not require the use of computers, is microform. There are other means of optically storing data and new methods are in development. An optical disc drive is a device in a computer that can read CD-ROMs or other optical discs, such as DVDs and Blu-ray discs.
