Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. A quantum computer is a device that performs quantum computing. They are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can be in superpositions of states. A quantum Turing machine is a theoretical model of such a computer, and is also known as the universal quantum computer. — Wikipedia

Photonic integration has focused on communications applications traditionally fabricated on silicon chips, because these are less expensive and more easily manufactured, and researchers are exploring promising new waveguide platforms that provide these same benefits for applications that operate in the ultraviolet to the infrared spectrum. These platforms enable a broader range of applications, such as spectroscopy for chemical sensing, precision metrology and computation.
