Questions

Figure 5.6 contains lots of little details. Keep me honest by checking to make sure that the H letters, question marks, zeros, ones, and arrows are all placed correctly on Bob’s side of the figure.
Repeat your work from Question 1, this time verifying the ones, zeros, and question marks in Eve’s column in Figure 5.10.
In carrying out the BB84 algorithm, Alice and Bob share some information out in the open. Bob shares all of his Hadamard choices, Alice announces which qubits are Hadamard agreement qubits, and Bob displays half of his Hadamard agreement bits. Justify the claim that making this information public doesn’t help Eve discover the key.
Make up an example to build your intuitions about the right distributive law for tensor products: ${"mathml":"<math style=\"font-family:stix;font-size:16px;\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mstyle mathsize=\"16px\"><mfenced><mrow><mi>x</mi><mo> </mo><mo>+</mo><mo> </mo><mi>y</mi></mrow></mfenced><mo> </mo><mo>⊗</mo><mo> </mo><mi>z</mi><mo> </mo><mo>=</mo><mo> </mo><mfenced><mrow><mi>x</mi><mo> </mo><mo>⊗</mo><mo> </mo><mi>z</mi></mrow></mfenced><mo> </mo><mo>+</mo><mo> </mo><mfenced><mrow><mi>y</mi><mo> </mo><mo>⊗</mo><mo> </mo><mi>z</mi></mrow></mfenced></mstyle></math>"}$ .
We began this chapter’s You can’t copy a qubit section by stating three laws for tensor products. Do we use all three of these laws in our argument about the truth of the No-Cloning...
