The present disclosure provides a method, device, equipment and readable storage medium for determining a quantum pulse, wherein a basic pulse corresponding to a basic logic gate is preset; including: when operating a quantum bit according to the quantum logic gate, changing the quantum logic gate The sub-logic gate is obtained by splitting; the sub-pulse corresponding to the sub-logic gate is searched in the basic pulse, and the qubit bit is operated according to the sub-pulse. In the solution provided by the present disclosure, in the method, device, device and readable storage medium provided by this embodiment, the basic pulse is preset, and when operating the qubit, the quantum logic gate to be used can be divided into Multiple sub-logic gates, and then find the sub-pulses corresponding to the sub-logic gates in the basic pulse, so that the read sub-pulses can be directly used to operate the qubits, avoiding the computational power consumption caused by generating pulses according to the quantum logic gates, Thus, the operation speed of the quantum computing system can be improved.
Description
technical field [0001] The present disclosure relates to computer technology, and more particularly to quantum computing systems. Background technique [0002] In a quantum computer, it is necessary to adjust the state of the qubit to make the qubit carry information. [0003] Qubits can be in 0, 1 or superposition state. By applying a pulse to the qubit, the state of the qubit can be changed, for example from |0> to |1>. [0004] Specifically, quantum logic gates (unitary transformation, U target ) pulses the qubit, e.g. via U target To operate on qubits, you can use the U based target The generated pulse is applied to the qubit, thereby changing the state of the qubit. [0005] However, in the case of complex logic and large amount of data, the quantum computing system generates U in real time based on the methods in the prior art. target The corresponding pulses cause quantum computing systems to slow down.
