New chip technology boost quantum computing power

An international team, including Chinese researchers, has demonstrated a large-scale integrated quantum photonic circuit, which may pave the way for manufacturing massive components for the realization of an optical quantum computer, a new study revealed. According to a study released by the University of Bristol, Integrated Quantum Photonics allows the routing and control of single particles of light with intrinsically high stability and precision, however to date it has been limited to small-scale demonstrations in which only a small number of components are integrated on a chip.

Scaling up these quantum circuits is of paramount importance to increasing the complexity and computational power of modern quantum information processing technologies, Xinhua reported.

In this study, published in the journal Science, researchers managed to integrate in a single chip 550 optical components, allowing the integrated photonic chip to entangle photons to incredible levels of precision. The chip was realized using a scalable silicon photonics technology, similar to today's electronic circuits.
