According to PhysicsWorld researchers from the University of Sao Paulo, Brazil and Max Planck Institute for the Science of Light, Erlangen, Germany have added another capability to the quantum computing toolkit by being the first to show that light beams of three different wavelengths can be entangled. This achievement could provide a way to create three-way optical communication links between elements of a quantum computer. This result was published in the recent issue of Science magazine.
