Quantum computing will change the way the world uses energy (qz.com)

The article is full of exaggerations. Quantums computers are more efficient for some kind of problems, not more efficient for every problem.

In particular this paragraph:

> And then there’s the price. Most modern classical supercomputers use between 1 to 10 megawatts of power on average, which is enough electricity to meet the instantaneous demand of almost 10,000 homes. As a year’s worth of electricity at 1 megawatt costs about $1 million in the US, this leads to multimillion-dollar price tags for operating these classical supercomputers. In contrast, each comparable quantum computer using 25 kilowatts of power costs about $25,000 per unit per year to run.

Since the current quantum computers are much more smaller than a supercomputer, it's ridiculous to say "each comparable quantum computer".
