University of Copenhagen Develops a ‘Quantum Leap’ Nanocomponent

By IQT News posted 24 Apr 2019

(ScienceDaily) Researchers at the University of Copenhagen have developed a nanocomponent that emits light particles carrying quantum information. Less than one-tenth the width of a human hair, the minuscule component makes it possible to scale up and could ultimately reach the capabilities required for a quantum computer or quantum internet. The research result puts Denmark at the head of the pack in the quantum race.
“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 quantum physics, we will need to scale systems up, which is what this invention allows for. To build a quantum computer or quantum internet, you don’t just need one photon at a time, you need lots of photons simultaneously that you can connect to each another,” explains Leonardo Midolo, who has been working towards this breakthrough for the past five years.
