Macroscopic and deterministic quantum feature generation via phase basis quantization in a cascaded interferometric system

Quantum entanglement is the quintessence of quantum information science governed by quantum superposition mostly limited to a microscopic regime. For practical applications, however, macroscopic entanglement has an essential benefit for quantum sensing and metrology to beat its classical counterpart. Recently, a coherence approach for entanglement generation has been proposed and demonstrated in a coupled interferometric system using classical laser light, where the quantum feature of entanglement has been achieved via phase basis superposition between identical interferometric systems. Such a coherence method is based on the wave nature of a photon without violating quantum mechanics under the complementarity theory. Here, a method of phase basis quantization via phase basis superposition is presented for macroscopic entanglement in an interferometric system, which is corresponding to the energy quantization of a photon.

The Impact of Narcissistic Leader on Subordinates and Team Followership: Based on “Guanxi” Perspective

Studies have shown that narcissistic individuals are more likely to become leaders in uncertain situations, while few studies paid attention to the relational mechanism, linking a narcissistic leader with subordinates and team attitudes and behaviors. Based on the “guanxi” and dominance complementarity theory, we examined the influencing mechanism of narcissistic leaders on subordinates and team followership (TF). Two-wave data collected from 326 employees in the manufacturing and technology industry in China supported our hypothesized model. We have found that narcissistic leaders have a negative impact on followership (F) and TF of subordinates; Supervisor–subordinate guanxi (SSG) and team leadership relationship identity play a partial mediating role between narcissistic leadership and subordinates and team followership. Furthermore, individual and team values play a moderating role in the process of influencing a mechanism. In other words, the higher the individual tradition and team power distance (PD), the less negative impact of leader narcissism on SSG and team leadership relationship identity. Theoretical and practical implications are discussed. We also offer several promising directions for future research.

Understanding the antecedents and outcomes of brand community-swinging in a poly-social-media context: a perspective of channel complementarity theory

PurposeThis study aims to examine the increasingly widespread phenomenon of brand community-swinging, which refers to a user's routine use of multiple brand communities of a brand across different social media. Drawing from channel complementarity theory, this study examines whether the complementarity of gratifications in four values (i.e. information value, entertainment value, social interaction value and self-presentation value) influences brand community-swinging and, in turn, cultivates brand loyalty.Design/methodology/approachA questionnaire was developed to collect relevant data from users of a well-known smartphone brand. The survey yielded a total of 351 useable responses, and a structural equation model approach was used to test the hypotheses.FindingsThe results indicate that three types of gratification complementarity (information value, social interaction value and self-presentation value) have a significantly positive impact on consumers' brand community-swinging, which further fosters brand loyalty.Originality/valuePrevious research predominantly focused on the motivations and outcomes of consumers' participation within a single-brand community, but little is known about the antecedents and outcomes of brand community-swinging in a poly-social-media context. This study contributes to the brand community literature by addressing this research gap.

Observations of Deterministic Quantum Correlation Using Coherent Light

Complementarity theory is the essence of the Copenhagen interpretation in quantum mechanics. Since the Hanbury Brown and Twiss experiments, the particle nature of photons has been intensively studied for various quantum phenomena such as anticorrelation and Bell inequality violation over the last several decades. Regarding the quantum features based on the particle nature of photons, however, no clear answer exists for how to generate such an entangled photon pair or what causes the maximum correlation between them. Here, we experimentally demonstrate the physics of quantumness on anticorrelation using well defined and nearly sub-Poisson distributed coherent photons, where a particular photon number is post-selected using a photon resolving coincidence measurement technique. As a results, unprecedented wavelength dependent first-order intensity correlation has been observed in the two-photon second-order intensity correlation with 99.9 % visibility, where this result demonstrates the anticorrelation theory in Scientific Reports 10, 7309 (2020) and opens the door to the on-demand quantum correlation control.

Unit commitment using complementarity

A need exists to optimally dispatch power generation to meet per-hour requirements on the power grid. This is a well documented and established problem called Unit Commitment (UC). It is commonly formulated as a Mixed Integer Linear Program (MILP), which utilizes intelligent solvers to produce a solution with speed and accuracy. The linear nature of MILP requires linear approximations of nonlinear constraints. This work introduces the Theory of Complementarity in order to remove integer variables, resulting in a continuous rather than a discontinuous solution space. This permits use of classical solution techniques, as well as nonlinear constraints, thereby increasing accuracy. A formulation is developed to demonstrate a proof of concept of the complementarity theory as used in UC. A subset of constraints will be used and the results will be compared against an MILP optimization, for 10-and 26-generator configurations. Similar trends in generator status and total cost are noted.

Comparison of Common Ground Models for Human--Computer Dialogue

Common ground processes [26] can improve performance in communication tasks [72, 42, 43, 24], and understanding these processes will likely benefit human--computer dialogue interfaces. However, there are multiple proposed theories with different implications for interface design. Fusaroli and Tylén [40] achieved a direct comparison by designing two models: one based on alignment theory and the other based on complementarity theory that encapsulated interpersonal synergy and audience design. The current research used these models, extending them to differentiate between interpersonal synergy and audience design. Few studies have tested multiple common ground models against tasks representative of envisioned human--computer interaction (HCI) applications. We report on four such tests, which allowed examination of generalizability of findings. Results supported the complementarity models over the alignment model, and were suggestive of the audience design variant of complementarity, providing guidance for HCI design that differs from contemporary approaches.

The Role of NPOs in Compulsory-Education Aid in China

Previous research has linked the activities of the non-profit sector to desired aid outcomes in China, such as improved public-service quality. However, issues related to the role of non-profit organizations (NPOs) in compulsory-education aid have received little attention. This study draws on Dennis Young’s complementarity theory – one of the most prominent non-profit theories – in examining the necessity and feasibility of NPO aid to Chinese compulsory education. In addition, it undertakes exploratory research in order to test an integrated model. Based on both data collected in surveys or interviews and statistical data from 263 Chinese county-level jurisdictions in five provinces (including 1 autonomous regions and 2 provincial-level municipalities), this study concludes that NPO aid can positively influence compulsory-education outcomes in mainland China. Its main contribution is to expand our understanding of NPOs and offer insights on how public managers can improve governance.
