I
will first introduce formation probability as a quantity which can determi
ne the universality class of a quantum critical system. In other words\, b
y calculating this quantity one can find the central charge and critical e
xponents of the quantum system. We will show that calculating this quantit
y boils down to finding Casimir energy of two needles. Then we will \;
briefly talk about Shannon mutual information as another quantity which c
an play similar role. Finally\, we will introduce post-measurement entangl
ement entropy as a tripartite measure of entanglement. We will show that t
his quantity is related to the Casimir energy of needles on Riemann surfac
es and can be calculated exactly for conformal field theories.
