The application of Integrated quantum photonic circuits to quantum photonics, [1] is seen as an important step in developing useful quantum technology. Single die photonic circuits offer the following advantages over bulk optics: Miniaturisation - Size, weight, and power consumption are reduced by orders of magnitude by virtue of smaller system ...
Since separating optical modes is a need for quantum computing, this technology may be helpful to miniaturize quantum computers (see linear optical quantum computing). Another example of a photonic integrated chip in wide use today in fiber-optic communication systems is the externally modulated laser (EML) which combines a distributed feed ...
For example, a coherent (classical) light input produces a coherent light output; a superposition of quantum states input yields a quantum light state output. [3] Due to this reason, people usually use single photon source case to analyze the effect of linear optical elements and operators.

Quantum processors are difficult to compare due to the different architectures and approaches. Due to this, published physical qubit numbers do not reflect the performance levels of the processor. This is instead achieved through the number of logical qubits or benchmarking metrics such as quantum volume , randomized benchmarking or circuit ...
For combinatorial optimization, the quantum approximate optimization algorithm (QAOA) [6] briefly had a better approximation ratio than any known polynomial time classical algorithm (for a certain problem), [7] until a more effective classical algorithm was proposed. [8] The relative speed-up of the quantum algorithm is an open research question.
Optoelectronics is based on the quantum mechanical effects of light on electronic materials, especially semiconductors, sometimes in the presence of electric fields. [2] Photoelectric or photovoltaic effect, used in: photodiodes (including solar cells) phototransistors; photomultipliers; optoisolators; integrated optical circuit (IOC) elements
