Quantum computing and the Landauer limit

Quantum computing?

Let’s start here:

This quote in particular caught my attention:

According to the report, which used the Landauer limit, “computing will not be sustainable by 2040, when the energy required for computing will exceed the estimated world’s energy production.“

The Landauer limit – the energy limit that’s been named after renowned IBM scientist Rolf Landauer – states that “each single bit operation must use an absolute minimum amount of energy.”

What is the Landauer limit?  

This is a good introduction in layman’s terms:
