measure_in_01_basis_collapse

Hi PacktPublishing,

I am currently learning Chapter03. of the book and having difficulty finding the way to collapse the measurement.
In the book, the measurement of qubit must collapse the state into one state but the function "measure_in_01_basis" cannot.
I tried to add collapsing part in the function but need help...
Would you kindly post the sample answer of Chapter 03 Problem 06?
Below is the code I tried.

Best wishes,
Jay Heo

Errata Page References wrong...

Hello,

All the Page references in the Errata that start after page 220 are off by 7 pages, for example the errata for page 220 is actually on page 227. When compared to the paperback version of the book.

bloch sphere simulated image not displayed in Chapter02 /SimulatingQubits.ipynb

This is the answer:

1. put these two lines out of the function "plot_bloch"(above):
   """
   import matplotlib.pyplot as plt
   from mpl_toolkits.mplot3d import Axes3D
   """
2. put "plt.show()" just below this line code:
   """
   plot_bloch(zero_to_one_qubit(10,90),color="xkcd:turquoise",ax=ax)
   """

The remaining parts are treated similarly.
