Dynamics of quantum coherence in Bell-diagonal states under Markovian channels

We study the curves of coherence for the Bell-diagonal states including $l_{1}$-norm of coherence and relative entropy of coherence under the Markovian channels in the first subsystem once. For a special Bell-diagonal state under bit-phase flip channel, we find frozen coherence under $l_{1}$ norm occurs, but relative entropy of coherence decrease. It illustrates that the occurrence of frozen coherence depends on the type of the measure of coherence. We study the coherence evolution of Bell-diagonal states under Markovian channels in the first subsystem $n$ times and find coherence under depolarizing channel decreases initially then increases for small $n$ and tend to zero for large $n$. We discuss the dynamics of coherence of the Bell-diagonal state under two independent same type local Markovian channels. We depict the dynamic behaviors of relative entropy of coherence for Bell-diagonal state under the bi-side different Markovian channel. We depict the dynamic behaviors of relative entropy of coherence for Bell-diagonal state under the bi-side different Markovian channel.Comment: 13 pages, 17 figure

Study on the Development Path of Rural Tourism in Chengdu in the Post-COVID-19 Era

Rural tourism can meet the needs of people who want to get close to nature and feel the pastoral scenery of rural homes, relax their body and mind, and facilitate the communication between urban and rural areas, accelerate rural economic development, improve the economic income of local farmers and promote rural revitalization. Therefore, it is of great significance to study the development of rural tourism. The global economy has been affected to varying degrees by the COVID-19 pandemic, with the tourism industry being a consumption-oriented industry that is not in demand. In the post-epidemic era, tourism needs to be adjusted and restored. Rural tourism has the characteristics of low aggregation, ecological protection, health and natural, and will become one of the main trends of tourism development

STUDENTS’ ENGAGEMENT IN COLLABORATIVE LEARNING GROUP SUPPORTED BY COMMUNICATION TOOLS: AN EMPIRICAL STUDY

Collaborative learning group in higher education is increasingly supported by communication tools, but there are still some problems regarding engagement. We examined students’ engagement in collaborative learning groups with the help of communication tool—Slack. Students’ motivation to engage in teamwork can be promoted through the openness of team members’ effort on Slack. Moreover, free-rider and sucker effect can also be relieved. Teamwork engagement can prompt students’ learning and work satisfaction. We proposed a research model and corresponding hypotheses. Surveys were issued online to graduate students at different time of our course. SmartPLS 3.0 was used to analyze data and test structure equations. We came to conclusions lastly as follows: mutual trust, social influence and reward valence are positively related to teamwork engagement, and teamwork engagement is positively related to personal success (i.e. learning and work satisfaction). However, the moderation role of task complexity between teamwork engagement and personal success is not supported. Theoretical and practical contributions are discussed. Research limitations and future research directions are also presented

Research on the Cultivation of Craftsmanship Spirit among Higher Vocational College Students and Integration of Industry and Education

This paper investigates the cultivation of craftsmanship spirit among higher vocational college students and the optimization and application of the integration of industry and education models, with the aim of promoting the development of craftsmanship spirit among students and advancing the integration of industry and education. Firstly, by analyzing the current status of cultivating craftsmanship spirit in higher vocational colleges, the necessity and importance of its development are explored. Secondly, considering the specific conditions in the Sichuan-ASEAN region, the feasibility and key factors of fostering craftsmanship spirit are discussed. Subsequently, this paper presents methods for optimizing industry-education integration and collaboration between colleges and enterprises based on craftsmanship spirit, aiming to facilitate deeper cooperation between higher vocational colleges and the industry. Finally, through case studies and empirical research, the practical effectiveness of the proposed model is validated, providing strong theoretical and practical support for educational and teaching reforms in higher vocational colleges
