Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum circuit capable of basic calculations and moving quantum computing closer to a becoming a reality.

University of Queensland researchers are among an international team to have made the first ever execution of a quantum calculation, a major step towards building the first quantum computers.

Guifre Vidal from the University of Queensland, has come up with a new method for performing renormalization group operations on entangled systems.
