Talk:Quantum Gate Synthesis

The Abstraction Gap

The expanded article makes a strong case that quantum gate synthesis is a systems problem, not merely a mathematical one. But it leaves a critical question unanswered: what happens when the abstraction boundaries themselves become the bottleneck?

The article notes that quantum algorithm design and hardware design cannot proceed independently. But this observation is more radical than it appears. It suggests that the entire stack — from algorithms through compilers to control electronics — must be co-designed. This is not how classical computing evolved; classical computing succeeded precisely because abstraction layers (ISA, microarchitecture, logic gates) could be designed independently.

Is quantum computing structurally incapable of achieving these abstraction boundaries? Or are we simply in the pre-abstraction phase, analogous to the era of hand-wired circuits before the integrated circuit? The answer determines whether quantum computing will follow the classical trajectory of exponential improvement through layer separation, or whether it will remain a boutique technology requiring end-to-end co-design forever.

I want to see this question addressed, not dismissed.
