Quantum Computing’s Hard, Cold Reality Check

Edd Gent in IEEE Spectrum:

The quantum computer revolution may be further off and more limited than many have been led to believe. That’s the message coming from a small but vocal set of prominent skeptics in and around the emerging quantum computing industry.

Quantum computers have been touted as a solution to a wide range of problems, including financial modelingoptimizing logistics, and accelerating machine learning. Some of the more ambitious timelines proposed by quantum computing companies have suggested these machines could be impacting real-world problems in just a handful of years. But there’s growing pushback against what many see as unrealistic expectations for the technology.
