error in instructions document #3

Closed aelmahdaoui closed 6 years ago

aelmahdaoui commented 6 years ago

In the instructions PDF, section 3.1.1 "An optimal quantum strategy", there is an error after the first formula saying "... where qubits a and c are held by Alice and b and c by Bob." c is mentioned twice

stephendiadamo commented 6 years ago

To align with the base example, it should be that 'a' and 'c' are with Alice and 'b' and 'd' are with Bob, but the subscripts above should switch 'b' with 'c'.

aelmahdaoui commented 6 years ago

Do you mean switch 'b' with 'c' and 'c' with 'b'?

stephendiadamo commented 6 years ago

I mean the 'c's on the left side of the tensor should be 'b's and the 'b's on the right side of the tensor should be 'c's.

Hi!

Thanks for pointing this out! I will update the instructions.
