... For four input bits of Alice, two pairs of NS-boxes on the level k = 1 allow Bob to make the guess of a value of any one of Alice’s bits as soon as he knows either a1 ⊕ AL or a3 ⊕ AR , which are the one-bit messages of the 1-box protocol. These can be encoded using the third box, on the level k = 2, ...

A digital computer is generally believed to be an efficient universal computing device; that is, it is believed able to simulate any physical computing device with an increase in computation time by at most a polynomial factor. This may not be true when quantum mechanics is ...
