Description
Technical Field
The invention relates to the field of quantum computing, in particular to a quantum computer.
Background
The quantum computer is a physical device which operates according to the law of quantum mechanics, can perform high-speed mathematical and logical operations, and stores and processes quantum bit information. Because quantum mechanics has the characteristics of superposition, coherence, entanglement and the like which are different from classical mechanics, a quantum computer can solve certain problems which are difficult to solve on the classical computer in a short time.
Like classical computers, quantum computers are essentially mathematical calculations performed to solve a problem, with the difference that the two ways of processing data are essentially different. Compared with a classical computer, the method can directly process a classical data form, the quantum computer needs to prepare the data in the classical form on an initial quantum state of the whole system of the quantum computer, evolve into a final state of the quantum computer system through a series of unitary operations (namely quantum logic gates), then carry out quantum measurement on the final state, and output an operation result.
When a quantum computer performs a quantum computing task, abnormal conditions may occur at each stage, such as an error problem in the process of compiling a quantum program. At present, the technical scheme of how to solve the problem of error in the execution process of the quantum computing task basically requires a technician to judge whether the error occurs through a result after the execution of a certain quantum computing task or after the execution of a certain experimental task. The scheme in the prior art needs to be manually participated in judging whether the quantum computer is abnormal or not in the running process, and can only be found when the execution result of the quantum computing task is wrong, so that the efficiency is extremely low. At present, under the condition that the number of quantum bits in a quantum chip is not large, the existing scheme can be barely supported, but with the continuous research of quantum technology, a large-scale or even ultra-large-scale quantum chip is inevitably generated in the future, and the quantum computing task to be solved is certainly more complex, and correspondingly, the abnormal situation that a quantum computer needs to face is more frequent and complex. If the prior art scheme is followed, the quantum computer will be extremely inefficient in performing quantum computing tasks.
Therefore, a quantum computer rack structure for improving the efficiency of identifying abnormal situations is proposed as a technical problem in the art.
It should be noted that the information disclosed in the background section of the present application is only for enhancement of understanding of the general background of the present application and should not be taken as an admission or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
