“…As same as Naor et al's scheme and Das et al's scheme [36], our scheme retains the advantage of singlepixel parallel processing, i.e., the color information of each pixel is encoded into n-qubit superposition state. Different from them in other aspects, we use the strategy of quantum expansion instead of pixel expansion.…”

“…In order to evaluate our scheme, we chose a classical VSS scheme [3] and two quantum VSS schemes [35], [36] as references, and compare our QVSS scheme with them from the following aspects: single-pixel parallel processing, pixel expansion, and the loss in resolution. For a more intuitive representation, the results of the comparison are shown in Table 4.…”

“…As far as we know, the literatures on how to use quantum mechanisms to solve VSS schemes are rare [35], [36]. In 2014, Song et al proposed a flexible (2 k , 2 k ) quantum image secret sharing (QISS) scheme [35], where the whole secret image is repeatedly encoded into a quantum state, and then split into sub-images as shares with multiple measurement operations.…”

Inspired by Naor et al.'s visual secret sharing (VSS) scheme, a novel n out of n quantum visual secret sharing (QVSS) scheme is proposed, which consists of two phases: sharing process and recovering process. In the first process, the color information of each pixel from the original secret image is encoded into an n-qubit superposition state by using the strategy of quantum expansion instead of classical pixel expansion, and then these n qubits are distributed as shares to n participants, respectively. During the recovering process, all participants cooperate to collect these n shares of each pixel together, then perform the corresponding measurement on them, and execute the n-qubit XOR operation to recover each pixel of the secret image. The proposed scheme has the advantage of single-pixel parallel processing that is not available in the existing analogous quantum schemes and perfectly solves the problem that in the classic VSS schemes the recovered image has the loss in resolution. Moreover, its experiment implementation with the IBM Q is conducted to demonstrate the practical feasibility.INDEX TERMS n-qubit superposition state, n-qubit XOR operation, quantum expansion, quantum visual secret sharing, single-pixel parallel processing, visual cryptography.
