  • Patent number: 10347605
    Abstract: Embodiments of the present invention disclose a computer system having a plurality of quantum circuits arranged in a two-dimensional plane-like structure, the quantum circuits comprising qubits and busses (i.e., qubit-qubit interconnects), and a method of formation therefor. A quantum computer system comprises a plurality of quantum circuits arranged in a two-dimensional pattern. At least one interior quantum circuit, not along the perimeter of the two-dimensional plane of the plurality of quantum circuits, contains a bottom chip, a device layer, a top chip, and a routing layer. A signal wire connects the device layer to the routing layer, wherein the signal wire breaks the two dimensional plane, for example, the signal wire extends into a different plane.

  • Publication number: 20190165244
    Abstract: The invention includes methods, and the structures formed, for multi-qubit chips. The methods may include annealing a Josephson junction of a qubit to either increase or decrease the frequency of the qubit. The conditions of the anneal may be based on historical conditions, and may be chosen to tune each qubit to a desired frequency.

  • Patent number: 10295582
    Abstract: Techniques relate to reading a qubit coupled to a microwave resonator. A microwave signal at a microwave resonator frequency is input to the microwave resonator that couples to the qubit. A microwave readout signal from the microwave resonator is output to a microwave to optical converter. The microwave readout signal includes a qubit state of the qubit. The microwave to optical converter is configured to convert the microwave readout signal to an optical signal. In response to the optical signal being output by the microwave to optical converter, it is determined that the qubit is in a predefined qubit state. In response to no optical signal being output by the microwave to optical converter, it is determined that the qubit is not in the predefined qubit state.

  • Publication number: 20190149246
    Abstract: A technique relates to communication of a quantum state. Polarization hardware is configured to receive a polarization encoded qubit and split the polarization encoded qubit into two qubits. A converter is coupled to the polarization hardware, and the converter is configured to convert the two qubits into a form suitable for a CNOT gate. The CNOT gate is configured to receive the two qubits such that a measurement result of a CNOT operation of the CNOT gate determines success of the communication of the quantum state.

  • Patent number: 9927636
    Abstract: Transducers and methods of making the same include a substrate having a cavity with a diameter that supports whispering gallery modes at a frequency of an input signal. A focusing structure in the cavity focuses the electric field of the input signal. A resonator directly under the focusing structure has a crystalline structure that generates an electro-optic effect when exposed to electrical fields. An electric field of the input signal modulates an output signal in the resonator via the electro-optic effect.
