“…Unlike classical systems, quantum coherence is a unique property of quantum systems that originates from the principle of quantum state superposition in quantum mechanics. It is a crucial characteristic of quantum systems and the essence of two-part and multipart quantum correlations [1][2][3][4][5]. Quantum coherence not only holds important theoretical significance, but can also can serve as a physical resource for emerging technologies such as quantum entanglement generation [6,7], quantum metrology [8][9][10], quantum thermodynamics [11][12][13], and quantum biology [14][15][16].…”

We propose a quantum coherence protection scheme for a two-qubit system by considering the exact evolution of multi-interacting qubits in a common reservoir. We ﬁnd that the l1 norm of coherence and the relative entropy of coherence can be noticeably enhanced by increasing the number of qubits in the weak/strong system-environment coupling regime, which contrasts sharply with the impact of coupling between qubits. Moreover, in the inﬁnite-time limit, all the coherence measures reach their steady values which are determined only by the number of qubits.

“…For improving the global search ability and avoiding becoming trapped into the local extremum, many improved or modified GSO algorithms have been developed [24][25][26]. Among these improved methods, a combination of the quantum computing principles and the swarm intelligence algorithms, such as quantum-inspired genetic algorithms [27], quantum evolutionary algorithm [28], quantum-inspired particle algorithm [29,30], and the quantum-inspired immune clonal algorithm [31][32][33],has drawn significant attention, since these methods can ensure a good tradeoff between the capacities for search space exploration and exploitation, thus maintaining an optimal diversity and size of the population throughout the search process [27][28][29][30][31][32][33].…”

Due to its advantages of high acceleration, reusability, environmental protection, safety, energy conservation, and efficiency, electromagnetic energy has been considered as an inevitable choice for future space launch technology. This paper proposes a novel three-level orbital launch approach based on a combination of a traditional two-level orbital launch method and an electromagnetic boost (EMB), in which the traditional two-level orbital launch consists of a turbine-based combined cycle (TBCC) and a reusable rocket (RR). Firstly, a mathematical model of a multi-stage coil electromagnetic boost system is established to develop the proposed three-level EMB-TBCC-RR orbital launch approach, achieving a horizontal take-off–horizontal landing (HTHL) reusable launch. In order to optimize the fuel quality of the energy system, an artificial intelligence algorithm parameters-sensitivity-based adaptive quantum-inspired glowworm swarm optimization (AQGSO)is proposed to improve the performance of the electromagnetic boosting system. Simulation results show that the proposed AQGSO improves the global optimization precision and convergence speed. By using the proposed EMB-TBCC-RR orbital launch system and the optimization approach, the required fuel weight was reduced by about 13 tons for the same launch mission, and the energy efficiency and reusability of the spacecraft was greatly improved. The spacecraft can be launched with more cargo capacity and increased payload. The proposed novel three-level orbital launch approach can help engineers to design and optimize the orbital launch system in the field of electromagnetic energy conversion and management.
