Description
Technical Field
The invention relates to the field of quantum computing, in particular to a quantum computer.
Background
A quantum computer is a physical device that operates according to the laws of quantum mechanics, and is capable of performing high-speed mathematical and logical operations, as well as storing and processing quantum bit information. Due to the fact that quantum mechanics has the characteristics of superposition, coherence, entanglement and the like different from classical mechanics, the quantum computer can solve certain problems which are difficult to solve on the classical computer in a short time.
The core of a quantum computer is mathematical computation for solving a certain problem, as in a classical computer, and the difference is that the two methods for processing data are essentially different. Compared with the classical computer which can directly process the classical data form, the quantum computer needs to prepare the classical data form on the initial quantum state of the whole system of the quantum computer, evolves the classical data form into the final state of the quantum computer system through a series of unitary operations (namely quantum logic gates), then carries out quantum measurement on the final state, and outputs the operation result.
When a quantum computer executes a quantum computing task, there is a possibility that an abnormal situation occurs in each stage, for example, an error problem occurs in a process of compiling a quantum program. At present, technical schemes for solving the problem of errors in the execution process of quantum computing tasks basically require technicians to judge whether an abnormality occurs according to results after a certain quantum computing task is executed or after an experimental task is executed. In the prior art, the scheme needs manual participation when judging whether the quantum computer is abnormal or not in the operation 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 quantum bit number in a quantum chip is not large, the quantum chip is still barely supported by adopting the existing scheme, but with the continuous research of quantum technology, a large-scale or even ultra-large-scale quantum chip is inevitably generated in the expected future, the quantum computing task needing to be solved at the time is definitely more complicated, and correspondingly, the abnormal condition that a quantum computer needs to face is more frequent and complicated. Still according to the prior art, the quantum computer will be very inefficient in performing quantum computing tasks.
Therefore, a quantum computer rack for improving the abnormal condition identification efficiency is provided, and a technical problem to be urgently solved in the field is provided.
It is noted that the information disclosed in this background section is only for enhancement of understanding of the general background of the application and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
