I am a postdoctoral student working on the geometry of entangled states and quantum information. I am trying to learn quantum stochastic calculus as well.

comment Programming for matrix manipulation
I used this matrix for checking. X = Table[Subscript[x, i, j], {i, 64}, {j, 64}]; Big[X,m,p,q,r,s] This is because of the program which we have written earlier. This makes a 64 x 64 matrix, which can be seen as a 16 x 16 block matrix, where each block is a diagonal matrix. Of course, my actual program is to write a more complicated operation instead of the simple one. This is just a test cast

comment Manipulating sparse array elements
Thanks a lot, especially for the second part. My arrays are very large. I only gave a small example for the question.
