With prevalent attacks in communication, sharing a secret between communicating parties is an ongoing challenge. Moreover, it is important to integrate quantum solutions with classical secret sharing schemes with low computational cost for the real world use. This paper proposes a novel hybrid threshold adaptable quantum secret sharing scheme, using an m-bonacci orbital angular momentum (OAM) pump, Lagrange interpolation polynomials, and reverse Huffman-Fibonacci-tree coding. To be exact, we employ entangled states prepared by m -bonacci sequences to detect eavesdropping. Meanwhile, we encode m -bonacci sequences in Lagrange interpolation polynomials to generate the shares of a secret with reverse Huffman-Fibonacci-tree coding. The advantages of the proposed scheme is that it can detect eavesdropping without joint quantum operations, and permits secret sharing for an arbitrary but no less than threshold-value number of classical participants with much lower bandwidth. Also, in comparison with existing quantum secret sharing schemes, it still works when there are dynamic changes, such as the unavailability of some quantum channel, the arrival of new participants and the departure of participants. Finally, we provide security analysis of the new hybrid quantum secret sharing scheme and discuss its useful features for modern applications.

Recent advancements, doping strategies and the future perspective of perovskite-based solid oxide fuel cells for energy conversion

Protonic ceramic electrochemical cells (including fuel cells (PCFCs) and electrolysis cells (PCECs)) are positioned as an eco-friendly means for realizing energy/chemical conversion at low (below 500 °C) and intermediate (500–800 °C) temperatures; as a result, R&D of PCFCs and PCECs are compatible with hydrogen energy and CO2 utilization programs that play an increasing role in global environmental practice. However, along with ionic transport, the majority of proton-conducting ceramic materials also exhibit electronic transport under oxidizing conditions and elevated temperatures. This feature negatively affects the performance of cells due to the short-circuit effect leading to a reduction in faradaic and energy efficiencies. In response, in order to achieve a compromise between high performance and high efficiency, the present review article aims at revealing the main factors contributing to undesirable electronic transport of materials used in PCFCs and PCECs, as well as possible solutions leading to its suppression for improving their efficiency.
