Future fruitfulness of the digital-analog quantum paradigm without full error correction

Establish whether, in the absence of a full-fledged quantum error-corrected computer, digital-analog quantum technologies will remain a fruitful avenue for quantum simulation and computing in the coming years.

Background

The article argues that fully error-corrected, large-scale quantum computers remain technologically out of reach in the near term, motivating hybrid digital-analog approaches that leverage native analog interactions with digital control. The author posits a conjecture about the continued utility of this paradigm under current technological constraints.

This raises a broad but explicit conjecture about the long-term viability and effectiveness of digital-analog quantum simulation and computing before fault-tolerant architectures become practical.
