Embodiment Construction
[0055] The third-party quantum information equality comparison method based on the replacement operation provided by the present invention, its specific implementation method is as follows:
[0056] Let |S|=r N , and the set S is as follows:
[0057] S={a (1,...,1,1) ,...,a (1,…,1,r) , a (1,...,2,1) ,...,a (1,...,2,r) ,...,a (r,…,r,1) ,...,a (r,…,r,r)}
[0058] Among them, S is an N-order array set, each element in S is taken from the set {0,1}, and both N and r are positive integers.
[0059] The following defines a special permutation operation on the set S
[0060]
[0061] Among them, k i ≤r, i=1,...,N, Wherein, l=1, 2, ..., r. The permutation operation π induces a new permutation operation τ,
[0062]
[0063] The set S here is essentially a set composed of multi-index arrays. In a quantum system, the permutation and transformation of the position of quantum particles can be realized through specific quantum exchange gates. This application provides...
