comment About Shor's error correcting algorithm
@LubošMotl So on a generic vector what would the encoding transformation do? Is it just a trivial projection operator?

comment About Shor's error correcting algorithm
@Lubos Motl In 4.2 I am not getting the notation. How is $\vert \bar{c} \rangle$ different from $\vert c_1, c_2, .., c_k, 0..(n-k)...0 \rangle$ ? I am not understanding what does 4.2 mean.

comment What is the current state of research about the Hayden-Preskill circuit?
@JohnRennie I think you are confusing something - what was closed was an earlier form of the question which had only the first line or two of what is written here - after the moderators closed that question, on my own I deleted that question and then reposted it with the additional details.

comment Is it possible to define a notion of temperature in a microcanonical ensemble?
@V.Moretti Well - the question is - whether this mathematical definition makes physical sense. A system in a microcanonical ensemble is an isolated system which can't exchange energy or particles or volume with anything else. Then how is the system equilibrating to a temperature? Can a system spontaneously determine its temperature without an infinite heat-bath? Isn't this the notion of temperature that leads to freaky things like negative temperature a finite system of spins? [...think of black-hole thermodynamics - isn't that a microcanonical ensemble?...]

comment canonical and microcanonical ensemble
In a microcanonical ensemble isn't it true that all microstates are equally probable and hence the probability distribution is just flat?
