Abstract

The invention provides a radio frequency circuit board structure for superconducting quantum bit measurement and control. The radio frequency circuit board structure comprises a plurality of first signal modulation modules and a control unit, each first signal modulation module is used for sending measurement and control instruction information generated by terminal equipment into the quantum chip; a second signal modulation module and a signal demodulation module are arranged in the control unit; the second signal modulation module is used for transmitting operation result information fed back by the quantum chip into the terminal equipment; the signal demodulation module is used for demodulating operation result information fed back by the quantum chip; wherein each first signal modulation module and the control unit are respectively and independently integrated and packaged into a whole; the control unit is selectively coupled with the plurality of first signal modulation modules through a communication network. Through the first signal modulation module and the control unit which are integrally packaged, a large amount of equipment debugging work is not needed when the terminal equipment performs a quantum measurement and control experiment, and the preparation time of the quantum measurement and control experiment is greatly shortened.

Description

technical field [0001] The invention relates to the field of quantum computers, in particular to a radio frequency circuit board used for superconducting qubit measurement and control. Background technique [0002] Manipulating the state information of qubits is usually realized by programming and controlling many instruments. These various instruments not only need to occupy a lot of space during use, but also, single devices do not match each other, and in many cases are not compatible with each other. . These factors require a lot of debugging before the quantum measurement and control experiment can start the experiment, which greatly restricts the development of quantum computers. Contents of the invention [0003] In order to solve the problem that a large amount of debugging is required before the use of quantum measurement and control mentioned in the background technology, the present invention proposes the following technical solutions: [0004] A radio frequen...
