Building on their earlier efforts to create a superconducting circuit integrated with magnetic elements, a team of researchers in the US (Argonne National Laboratory, University of Illinois) is investigating whether magnons could partner with microwave photons to ensure that microwaves can only travel in one direction, thereby essentially eliminating noise. They will be testing known and new material systems to find candidates that can handle an ultracold environment and operate in a real quantum device. According to the researchers if they are successful, it is possible to have magnetic structures directly integrated with quantum circuitry. The work could also apply to non-quantum devices for sensing and communication, such as in Wi-Fi or Bluetooth technologies. This capability presents unique opportunities for manipulating quantum information…read more.
