    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.

    Abstract: An RF bandpass filter includes a cascaded series of a first subfilter and a second subfilter. Each subfilter includes a respective inverter, voltage-controlled capacitor and inductor. A first selected one of the first subfilter and the second subfilter is a pseudo low pass filter and a second selected one of the first subfilter and the second subfilter is a pseudo high pass filter. The RF bandpass filter is configured to separately control a bandwidth and center frequency of output RF energy. The bandwidth may be controlled to be substantially fixed over a significant substantial range. The center frequency and bandwidth are controlled by adjusting a voltage input to one or more of the voltage-controlled capacitors.

  • Patent number: 8994470
    Abstract: A circuit substrate has three wiring layers, wherein a signal line is formed in a first wiring layer; a ground plane is formed in a second wiring layer; a resonant line is formed in a third wiring layer. A circumferential slit is formed in the ground plane, wherein an island electrode separated from the ground plane is formed inside the slit. The left end of the resonant line is connected to the island electrode through an interlayer-connecting via, while the right end of the resonant line is connected to the ground plane through an interlayer-connecting via. A transmission line (or a microstrip line) is formed using the signal line and the ground plane, and therefore a complex resonator is formed to embrace the transmission line. This achieves band elimination with regard to a signal component of a resonance frequency among signals propagating through the microstrip line.
