The rapid evolution of quantum hardware necessitates an adaptable static analysis framework for validating quantum programs. In this work, we introduce SHARP, a rule-based static analysis framework designed for OpenQASM that decouples hardware-specific constraints from the validation engine. By employing a rule-based approach, SHARP allows quantum computing services to validate programs against evolving instruction set architectures (ISAs) without having to modify the core analysis engine. SHARP achieves this by ingesting ISA descriptions as standalone data, making the validation engine resilient to hardware updates. Furthermore, the framework employs an analysis-driven validation mechanism that enables multi-stage validation, simplifying rule construction and enhancing extensibility. We demonstrate how SHARP supports hardware-specific validation tasks and discuss its impact on quantum software development, including language decoupling, program-level constraint validation, and feature access control. Our findings suggest that SHARP provides a path toward a scalable and maintainable programming interface for quantum computing.

After publishing my book "Quantum Computing Architecture and Hardware for Engineers: Step by Step" [1] (now I call it Volume I), in which spin qubit and superconducting qubit quantum computers were covered, I decided to continue to write the second volume to cover the trapped ion qubit quantum computer, which was also taught in my EE274 class. I follow the same structure as in Volume I by discussing the physics, mathematics, and their connection to laser pulses and electronics based on how they fulfill the five DiVincenzo's criteria. I also think it would be a good idea to share the second volume on arXiv so that more people can read it for free, and I can continue to update the contents. As of July 2025, I have finished the trapped ion quantum computer part. In the future, I plan to write more critical topics in a step-by-step manner to bridge engineers who did not receive rigorous training in Physics to the quantum computing world.
