Superconducting quantum hybrid system and computer equipment

Abstract

The invention discloses a superconducting quantum hybrid system and computer equipment, and relates to the field of quantum computing. The superconducting quantum hybrid system comprises a silicon carbide epitaxial layer and a superconducting quantum bit line. A nitrogen hole color center is contained in a specified region of the silicon carbide epitaxial layer; the nitrogen hole color center is formed by injecting nitrogen ions into the silicon carbide epitaxial layer in a specified area; the superconducting quantum bit line is located on the surface of the silicon carbide epitaxial layer; the superconducting quantum bits corresponding to the superconducting quantum bit lines are coupled with the solid-state defect quantum bits corresponding to the nitrogen hole color centers in the designated area. According to the scheme, the formation position and number of the NV color centers can be accurately controlled in an ion injection mode, so that coupling between the solid-state defect quantum bits and the superconducting quantum bits is controlled, and the superconducting quantum bits with short coherence time can store information into the solid-state defect quantum bits with long coherence time; the de-coherence time of the information is increased, and an effective number of quantum calculation operations can be realized more easily within the coherence time.

technical field [0001] This application relates to the field of quantum computing, in particular to a superconducting quantum hybrid system and computer equipment. Background technique [0002] A quantum computer is a computer that operates on the fundamental principles of quantum computing. The most significant difference from classical computers is that they can use the superposition principle and the characteristics of quantum entanglement, and have powerful parallel processing capabilities. [0003] Based on different physical systems, researchers have proposed different concepts of quantum computers, including superconducting qubits based on Josephson junctions. The superconducting qubit uses the core component of the Josephson junction (equivalent to the nonlinear inductance in the harmonic oscillator) to construct a multi-level system, and the superconducting qubit built by the Josephson structure is easy to expand and easily coupled into multiple qubits , to achiev...
