Question: Q . 3 : In a BB 8 4 protocol with polarized photons, instead of two basis - sets making 4 5 angle, two basis

Q.3: In a BB84 protocol with polarized photons, instead of two basis-sets making 45 angle, two basis-sets, H & T, that are at 60 angle, are chosen.
(a) If Alice sends 4n random bits with randomly selected basis-sets from H & T, how many total bits will be correctly interpreted by Bob?
(b) Now if Alice and Bob exchange the 4n bases used for the 4n bits, their bases agree with each other for Nb bits. What is Nb value?
(c) Now they exchange Nb2 bits for which they use the same bases. How many bits will they agree upon if Eve is intercepting with the same H & T bases?
