Drawing Penrose diagram figures

Click For Summary
Creating Penrose diagrams can be challenging for those who struggle with manual drawing. There is interest in finding dedicated software for generating these diagrams efficiently. One user successfully utilized Mathematica to parameterize and plot the necessary lines and shapes. The discussion highlights the need for accessible tools for visualizing complex concepts in theoretical physics. Overall, there is a call for more user-friendly options in drawing Penrose diagrams.

I need to create a figure of a Penrose diagram and I wonder if there is a dedicated program to this task. I know it's only a bunch of nested squares and lines but some people like me are simply uncapable of drawing anything by hand!

This probably isn't helpful for you, but I parameterized the u = const and v = const lines (well, their conformal equivalents) and plotted them using mathematica. Then I plotted a square around them =).
 

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
