Vaire Computing

[coppice]

Vaire is a startup that seems to be trying to tackle an idea known about since soon after Landauer's principle was published in the 1960s. That if you could compute reversibly, your theoretical minimum amount of energy to compute could tend to zero, rather than tend to the Landauer limit. The Landauer limit is the theoretical energy inherent in flipping a bit, as opposed to the massive real world energy we currently take to flip bits, because we lose so much to leakage and resistance. I've heard the name Vaire a few times over the last 3 or 4 years, but I just saw something that says they aim to have something working this year. Does anyone know more about them? All I can find is really vague. Unless they are doing something at superconducting temperatures, I can't see how anything major can be saved over current solutions, but I don't see superconducting mentioned in the stuff I have seen. There have been some university demonstrations of Landauer erasure in superconductors.
