Extensible quantum information processing system and method

Abstract

The invention discloses an extensible quantum information processing system and method, and relates to the technical field of quantum computing. The structure of the extensible quantum information processing system comprises a columnar diamond sample, an optical system, a microwave system, a magnetic field system, a carbon nanotube double-quantum-dot sample, a low-temperature system, a data acquisition system and an electric control system. The invention provides a carbon nanotube-spinning hybrid quantum system, wherein microwave signals and a magnetic field are applied to an area where each group of nitrogen vacancy centers and quantum dots are located, and magnetic dipole-dipole interaction exists between electrons of each group of nitrogen vacancy centers and the quantum dots; and by controlling a magnetic field and a microwave signal, indirect coupling between two nitrogen-vacancy centers which are spaced by a micron dimension can be realized through the action of the carbon nano tube, and quantum entanglement between the two nitrogen-vacancy centers in a long distance is realized, so that an extensible quantum information processing method is provided.

Description

technical field

[0001] The present invention relates to the fields of quantum entanglement and quantum computing, and more specifically, relates to a scalable quantum information processing system and method. Background technique

[0002] Similar to classical computers, quantum computers also have the concept of bits—qubits. Classical bits have two states, namely '0' or '1'. For a classical bit, it is in a certain state, not '0'. ' is '1', but the qubit is different, it is in a superposition state, written in the notation of quantum mechanics is |Ψ>=α|0>+β|1>, where α and β are complex numbers, and satisfy| α | 2 +|β| 2 =1. Because the qubit is in a superposition state, it will be affected by time and the environment, and the results of multiple measurements may not be the same.

[0003] Assembling a quantum computer requires finding a suitable substance to act as a qubit. The qubit is the carrier of quantum information and calculations, and the decoherence time...
