Abstract
Systems and methods are provided for routing quantum signals in a quantum computing system. An exemplary method includes providing a waveguide configured to be coupled to at least two modules and a nonlinear element, the waveguide configured to facilitate exchange of quantum information between the at least two modules, the waveguide having at least two waveguide modes, each waveguide mode having a respective frequency; providing a first module couplable to the waveguide at a first module frequency corresponding to a first waveguide mode and a second module couplable to the waveguide at a second mode frequency corresponding to a second waveguide mode; and driving the waveguide via the nonlinear element at a difference frequency equal to a difference between the first module frequency and the second module frequency, thereby causing exchange of quantum information between the first and the second modules.
