Wireless Josephson parametric converter

A method of operating a wireless converter, the method comprising:

• wirelessly receiving pump energy at a first frequency by a first plurality of Josephson junctions formed on a substrate and connected in a ring;
• wirelessly receiving a signal at a second frequency from a first antenna formed on the substrate, wherein a first half of the first antenna is connected to a first node between two Josephson junctions on a first side of the ring and a second half of the first antenna is connected to a second node between two Josephson junctions on a second side of the ring;
• wirelessly receiving an idler at a third frequency from a second antenna formed on the substrate, wherein a first half of the second antenna is connected to a third node between two Josephson junctions on a third side of the ring and a second half of the second antenna is connected to a fourth node between two Josephson junctions on a fourth side of the ring;
• converting pump energy to the second frequency and third frequency by the plurality of Josephson junctions;
• and
• wirelessly emitting an altered signal with the first antenna.
