Teams around the world are working to develop quantum technologies. The focus of researchers based at the Center for Hybrid Quantum Networks (Hy-Q) at the University of Copenhagen's Niels Bohr Institute is on developing quantum communication technology based on light circuits, known as nanophotonic circuits. The UCPH researchers have now achieved a major advancement.
"It is a truly major result, despite the component being so tiny," says Assistant Professor Leonardo Midolo, who has been working towards this breakthrough for the past five years.
Research - Team - Component - Router - Information
The research team has invented a component, called a nanomechanical router, that emits quantum information carried by light particles (photons) and routes them into different directions inside a photonic chip. Photonic chips are like computer microchips -- only, they use light instead of electrons. The component merges nano-opto-mechanics and quantum photonics -- two areas of research that, until now, have never been combined. Most spectacular of all, is the size of the component, just a tenth that of a human hair. It is this microscopic size that makes it so promising for future applications.
"Bringing the worlds of nanomechanics and quantum photonics together is a way to scale up quantum technology. In quantum physics, it has been a challenge to scale systems. Until now, we have been able to send off individual photons. However, to do more advanced things with...
