This isn't really a question as such, but rather an add for another stackexchange proposal which is likely of interest to at least a few of the users here. I know this is off topic, even for meta, so I'll understand if this gets closed/deleted. I only take the liberty of posting this following a suggesting from one of the mods.
At the moment, there is a Theoretical Physics proposal on Area 51, which is at 77% commitment. There are already enough low rep users, but in order to progress to beta we still need more users with over 200 rep. Although there is currently a Physics.SE it is at a pretty basic level (think math.se rather than MathOverflow), and so the current proposal is for a physics site made in the image of this site (TCS.SE) which would be explicitly research level only.
TCS.SE currently has quite a lot of quantum info people for whom the new site may hold some interest. It might also be of interest from the perspective of statistical mechanics, which is showing up more and more in TCS.
In any case, if this proposal sounds of interest to you, I hope you'll consider committing so that we can progress to beta soon and make the site a reality.
