A Critical Comment on 'Entropy Computing: A Paradigm for Optimization in Open Photonic Systems'

TL;DR

This paper critically examines Entropy Quantum Computing (EQC), highlighting that current claims lack sufficient rigor and do not outperform classical algorithms, though further research is needed to evaluate its potential.

Contribution

It provides a rigorous critique of EQC's claims and assesses its current limitations compared to classical computing methods.

Findings

Current EQC claims are not rigorously supported.

EQC does not outperform classical algorithms on conventional computers.

Further research is necessary to evaluate EQC's long-term potential.

Abstract

In this article, we take a close look at Entropy Quantum Computing (EQC), a computational paradigm developed by Quantum Computing Inc. (QCi), which deviates from mainstream quantum computing by embracing rather than battling environmental noise and decoherence arXiv:2407.04512 . In their words this approach purports EQC as an open quantum system that turns "entropy into super-power fuels of its computing engine". We show that some of the claims in the main article can be made more rigorous, and yet these are still not good enough to beat state of the art classical algorithms on conventional classical computers. Note that these conclusions reflect the technology's current early stage of development and are not meant to discourage its pursuit. Continued rigorous exploration is necessary to fully assess the long-term viability and potential advantages of this distinct computational approach.
