1Productivity
If conventional pulse generation systems are used, then pulse generation capability is provided, but resource requirements and system complexity increase
Solution Approach 1:
The patent replaces conventional hardware-based pulse generation systems with a software-defined approach. A programming subsystem generates pulse programs that are compiled and executed by a quantum controller, substituting mechanical/electronic pulse generation hardware with software-based control. This reduces physical system complexity while maintaining pulse generation capability.
Solution Approach 2:
The quantum controller is designed to execute compiled pulse programs for multiple different quantum algorithms and pulse sequences. Rather than requiring dedicated hardware for each pulse type, a single universal controller handles diverse pulse generation needs through software programming, reducing overall system complexity.
2Adaptability or versatility
If conventional pulse generation systems are used, then basic pulse control is achieved, but flexibility in adapting to different quantum elements and algorithms is reduced
Solution Approach 1:
The system employs dynamic pulse program generation where the programming subsystem creates pulse programs based on runtime analysis of quantum element characteristics and algorithm requirements. The pulse characteristics (amplitude, duration, frequency) are determined dynamically rather than being fixed in hardware, enabling adaptation to different quantum elements without additional hardware complexity.
Solution Approach 2:
The patent changes the approach from fixed hardware parameters to software-defined parameters. Pulse program parameters such as amplitude, duration, and timing are specified in software and can be modified without physical reconfiguration. This allows the same hardware to adapt to different quantum elements by changing software parameters rather than hardware configuration.
3Adaptability or versatility
If high-level pulse programs are compiled and executed dynamically, then pulse generation flexibility improves, but processing time may increase
Solution Approach 1:
The programming subsystem performs preliminary analysis and generates pulse programs before execution. By analyzing quantum element characteristics and algorithm requirements in advance, the system prepares optimized pulse programs that can be executed efficiently with minimal runtime delays, reducing overall processing latency.
Solution Approach 2:
The system maintains continuous operation by compiling and executing pulse programs in an optimized workflow. The quantum controller continuously executes compiled programs without significant idle time, and the programming subsystem efficiently generates new programs based on runtime analysis, maintaining continuous useful action while enabling real-time adaptation.

AI summary
A system comprises pulse program compiler circuitry operable to analyze a pulse program that includes a pulse operation statement, and to generate, based on the pulse program, machine code that, if loaded into a pulse generation and measurement circuit, configures the pulse generation and measurement circuit to generate one or more pulses and/or process one or more received pulses. The pulse operation statement may specify a first pulse to be generated, and a target of the first pulse. The pulse operation statement may specify parameters to be used for processing of a return signal resulting from transmission of the first pulse. The pulse operation statement may specify an expression to be used for processing of the first pulse by the pulse generation and measurement circuit before the pulse generation and measurement circuit sends the first pulse to the target.
