A target label code and a target time code are issued through an upper computer through a main control module; the control signal generation module is controlled to generate a quantum bit control signal; the control signal corresponding to the quantum logicgate is pre-stored in the main control module in the form of the first standard signal; a to-be-processed signal is generated by adopting a target tag code and a form of storing a first address code corresponding to the first standard signal in the main control module; the capacity storage requirement on the main control module is greatly reduced from the source; according to the quantum bit control method and the quantum bit control device, the quantum bit control signal can be rapidly provided, the response speed of the control signal generation module is greatly improved, and the speed of post-stage quantum operation is ensured.

Description

technical field [0001] The invention belongs to the technical field of signal processing, in particular to a qubit control signal generating system. Background technique [0002] Quantum chips are the core structure of quantum computers, and qubits are the basic computing units of quantum chips. When the quantum chip is running, it is necessary to provide reliable control signals to the qubits on the quantum chip to realize quantum testing. The qubit control signal acts on the qubits of the quantum chip, which can cause the quantum state of the target qubit to undergo a controllable and specified change, so as to realize the operation of the quantum logic gate. In the actual operation process, it is necessary to implement a series of quantum logic gate operations on the qubit, so the number and length of the qubit control signals will be greatly increased due to the type and number of quantum logic gate operations. [0003] One method of generating qubit control signals in...
