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).
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 ...
Integrated quantum photonics, uses photonic integrated circuits to control photonic quantum states for applications in quantum technologies. [1][2] As such, integrated quantum photonics provides a promising approach to the miniaturisation and scaling up of optical quantum circuits. [3] The major application of integrated quantum photonics is ...
Photonics. Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in the form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. [1][2] Photonics is closely related to quantum electronics, where quantum electronics deals with ...
Jiuzhang (quantum computer) 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. [1]
A photonic integrated circuit (PIC) or integrated optical circuit is a microchip containing two or more photonic components that form a functioning circuit. This technology detects, generates, transports, and processes light. Photonic integrated circuits use photons (or particles of light) as opposed to electrons that are used by electronic ...
Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. [1][2][3][4][5] The silicon is usually patterned with sub-micrometre precision, into microphotonic components. [4] These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication ...
1980. [] Paul Benioff describes the first quantum mechanical model of a computer. In this work, Benioff showed that a computer could operate under the laws of quantum mechanics by describing a Schrödinger equation description of Turing machines, laying a foundation for further work in quantum computing.
