Superconducting quantum hybrid system and computer equipment

Abstract

The present application relates to a superconducting quantum hybrid system and computer equipment, and relates to the field of quantum computing. The superconducting quantum hybrid system includes: a silicon carbide epitaxial layer and a superconducting qubit circuit; a designated area of ​​the silicon carbide epitaxial layer contains a nitrogen hole color center; the nitrogen hole color center is to inject nitrogen ions into the silicon carbide epitaxial layer in a designated area. The superconducting qubit circuit is located on the surface of the silicon carbide epitaxial layer; the superconducting qubit corresponding to the superconducting qubit circuit is coupled with the solid-state defect qubit corresponding to the nitrogen hole color center in the designated area. The above scheme can accurately control the position and number of NV color centers formed by ion implantation, so as to control the coupling between solid-state defect qubits and superconducting qubits, so that superconducting qubits with short coherence time can store information to coherent qubits. In solid-state defect qubits with long time, the decoherence time of information is increased, and it is easier to realize an effective number of quantum computing operations within the coherence time.

Description

technical field [0001] The present 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 ideas for quantum computers, including superconducting qubits based on Josephson junctions. Superconducting qubits use the Josephson junction as the core element (equivalent to the nonlinear inductance in the harmonic oscillator) to construct a multi-level system, and the superconducting qubits constructed by the Josephson structure are easy to expand and couple into multiple qubits. , for quant...

Problems solved by technology

[0004] In the above scheme, the coherence of the superconducting qubit based on the Josephson structure is poor, and the coherence time is short, so it is difficult to realize an effective number of quantum computing operations within the coherence time
