To optimize the algorithms for the dihedral hidden subgroup problem,we present a new algorithm based on lattice basis reduction *** n\120,we reduce the dihedral hidden subgroup problem to shortest vector problem.A subroutine is given to get a transition quantum state by constructing a phase filter function,and then the measurement basis are derived based on the lattice basis reduction algorithm for solving low density subset sum ***,the parity of slope s is revealed by the *** algorithm needs preparing mn quantum states,m qubits to store and O(n2)classical space,which is superior to existing algorithms.

To search for a target n-product Boolean vector of fixed weight d, we propose an important method involving the notion of a fixed-weight "vector label" accompanied with a vector label restoration algorithm. Based on these, we present a new quantum algorithm designed to search for a fixed-weight target whose computation complexity, specifically O ((Cdn+1)^(1/2)) , is better than that for a classical algorithm. Finally, we use the procedure to search for the NTRU private key as an example to verify the efficiency of the new algorithm in searching for fixed-weight target solutions.

In this paper, based on the implementation of semiclassical quantum Fourier transform, we first propose the concept of generation vector of ternary binary representation, construct the generation function's truth table, prove that the generation vector of ternary binary representation is one kind of k 's NAF representation and further find that its number of nonzero is not more than [(「logk」+1) /2]. Then we redesign a quantum circuit for Shor's algorithm, whose computation resource is approximately equal to that of Parker (Their requirements of elementary quantum gate are both O (「logN」3), and our circuit requires 2 qubits more than Parker's). However, our circuit is twice as fast as Parker's.

A new collusion attack on Pour-like schemes is proposed in this paper. Then, we present a collusion-free centralized multicast key management scheme based on characteristic values of members. The re-keying method that other group members calculate new keys when a member is joining or leaving is also designed. It achieves forward secrecy and backward secrecy. Compared with typical existing centralized schemes, the storage of Group Key Controller (GKC) in our scheme halves the storage overhead of others, and communication overhead of GKC is 2 in case of joining re-keying. Especially, the leaving re-keying overhead is and the overall performance is excellent.

This paper characterizes two important properties of the photon number distribution of the heralded pair coherent state (HPCS) photon source. The formula of secret key generation rates for the decoy-state quantum key distribution with intensity fluctuation source is proved to hold true for the HPCS photon source. By numerical simulations, we show that the three-intensity decoy-state protocols for the HPCS photon source is efficiently getting close to the ideal decoy-state method. Moreover, we find that the HPCS source is more robust against intensity fluctuation than the weak coherent photon (WCP) source, but less stable than the heralded single photon source (HSPS).
