Abstract
Metamaterial waveguides and shielded bridges are employed to improve the scalability and routing of quantum computing circuits. A metamaterial waveguide includes a signal conductor that has a periodic array of lumped element resonators distributed along and electrically coupled to a signal conductor. The periodic array of lumped element resonator pairs defines a bandgap within an operating bandwidth of the waveguide. Qubits can communicate within the operating bandwidth of the waveguide and communications via the waveguide can be controlled by changing a center frequency of the qubits. A shielded bridge is used to cross over high frequency communications and control CPW's in a quantum computing circuit. The shielded bridge includes a signal bridge that is elevated and extends over a separate CPW, and a ground bridge positioned between the signal bridge and the separate CPW.
