Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pulses are generated in real-time based on quantum logic gates, then the system can manipulate qubits accurately, but the operation speed becomes slow due to high computing resource consumption
Solution Approach 1:
The patent pre-generates and stores basic pulses corresponding to fundamental quantum logic gates (such as Pauli gates and Hadamard gates) before actual quantum computation. When a complex quantum logic gate needs to be executed, it is decomposed into a sequence of these basic gates, and the corresponding pre-generated pulses are retrieved and combined, eliminating the need for real-time pulse generation and significantly improving operation speed while maintaining manipulation accuracy.
2Adaptability or versatility
If complex quantum logic gates are implemented directly, then complete quantum operations can be performed, but computing power consumption increases and operation speed decreases
Solution Approach 1:
The patent decomposes complex quantum logic gates into sequences of basic quantum logic gates (such as breaking down a general single-qubit gate into Pauli gates and Hadamard gates). Each basic gate has a corresponding pre-generated pulse stored in memory. By segmenting complex operations into basic components, the system retrieves and combines pre-generated pulses instead of generating new pulses in real-time, reducing computing power consumption while maintaining complete quantum operation capability.
3Reliability
If real-time pulse generation is performed for each quantum logic gate, then accurate qubit manipulation is achieved, but the system running speed becomes slow
Solution Approach 1:
The patent pre-generates pulses for basic quantum logic gates and stores them in a memory device before actual quantum computation begins. During computation, when a quantum logic gate needs to be executed, the system retrieves the corresponding pre-generated pulse from memory and applies it to the qubit. This preliminary preparation eliminates real-time pulse generation overhead, significantly improving system running speed while maintaining accurate qubit state control through the use of precisely engineered pre-generated pulses.

AI summary
Provided are a quantum pulse determining method, apparatus, device and readable storage medium, where basic pulses corresponding to basic logic gates are set in advance, the method including: when manipulating a qubit according to a quantum logic gate, splitting the quantum logic gate to obtain sub-logic gates; and searching for sub-pulses corresponding to the sub-logic gates among the basic pulses, and manipulating the qubit according to the sub-pulse. Basic pulses are set in advance in the method, apparatus, device and readable storage medium provided by the embodiments. When a qubit is to be manipulated, the quantum logic gate can be split into multiple sub-logic gates, and then sub-pulses corresponding to the sub-logic gates are searched for among the basic pulses. Thus, sub-pulses read can be used directly to manipulate the qubit, avoiding the computing power consumed in generating pulses according to the quantum logic gate, thereby improving an operation speed.
