... suggest that the probability we detect the photon at x should simply be the sum of the probability of detecting it at x if only slit 1 were open and the probability if only slit 2 were open. In other words the outcome should no longer be consistent with the interference pattern. If you were to actua ...

Quantum cryptography

... Alice and Bob agree on a random permutation of the bits in the key They split the key into blocks of length k Compare the parity of each block. If they compute the same parity, the block is considered correct. If their parity is different, they look for the erroneous bit, using a binary search in th ...

If it is a tail, she encodes in 45/135 basis. 3. Each bit is encoded as 0 or 1 in the chosen basis. 4. Bob recei ...
