Description

The idea of using a quantum system to simulate another quantum system was proposed by R.P Feynman at the beginning of 80's. Since then many theoretical and experimental discoveries (e.g. Shor's algorithm, KLM scheme) followed, giving the birth to quantum information processing science.
Photons are one of the preferred vehicles to implement quantum logic gates and many examples of discrete components linear optics quantum computing devices have been realized.
Silicon photonics offers the possibility to implement linear optics quantum gates in a single integrated circuit. Given its high refractive index and low dispersion, silicon represents a high quality material for light guiding devices.
Two INFN experiments on silicon photonics in collaboration with IHP foundry have been funded by CSN5 (SPE in 2017-2019 and QUICHE in 2020).
We discuss the proposal of a quantum information processing silicon photonic integrated circuit working within ITU C-band (1550 nm).
