QuantumCore targets chip-scale magnetless circulators to shrink superconducting quantum readout hardware footprint
  • QuantumCore launched development of chip-scale, magnetless cryogenic circulators to replace ferrite-based units in superconducting quantum computer readout chains.
  • Plan targets smaller cryogenic footprints, higher-density routing, fewer discrete components, connectors, and cables as systems scale to thousands of channels.
  • Research will pursue RF switching and spatiotemporal modulation to deliver nonreciprocal microwave routing without permanent magnets.
  • Strategy centers on integration with its PCM/superconducting multiplexing microchips to build more integrated cryogenic modules for control-to-QPU infrastructure.
  • Program runs under a University of Waterloo sponsored research agreement, with plans to seek non-dilutive federal and provincial grant funding.
