Embodiment Construction

[0028] For the sake of brevity, conventional techniques related to semiconductor and / or superconducting device and integrated circuit (IC) fabrication may or may not be described in detail herein. Furthermore, various tasks and process steps described herein may be incorporated into a more comprehensive process or process having additional steps or functions not described in detail herein. In particular, the individual steps in the fabrication of semiconductor and / or superconducting devices and semiconductor / superconductor-based ICs are well known, and therefore, for the sake of brevity, many conventional steps will only be briefly mentioned herein, or well-known processes not provided. The details are omitted entirely.

[0029] Turning now to an overview of the technology more specifically related to aspects of the present invention, in a state of the art N qubit readout resonator in a superconducting quantum processor, in one case there are N inputs carrying the readout sign...

Abstract

A technique relates to a router. The router includes a qubit signal distributor, a readout signal distributor, and diplexers communicatively coupled to the qubit signal distributor and the readout signal distributor.

Description

technical field [0001] The present invention relates generally to superconducting devices, and more particularly to reducing the number of input lines to a superconducting quantum processor installed in a dilution refrigerator using frequency division multiplexing components. Background technique [0002] The phrase "superconducting quantum computing" refers to the use of quantum computers in superconducting electronic circuits. Quantum computing studies the application of quantum phenomena to information processing and communication. Various models of quantum computing exist, the most popular models incorporating the concepts of qubits and quantum gates. A qubit can be thought of as a generalization of a bit that has two possible states but can be in a quantum superposition of the two states. Quantum gates can be thought of as a generalization of logic gates, since a quantum gate describes the transition from its original state that one or more qubits will undergo after a...
