Freely Scalable Quantum Technologies using Cells of 5-to-50 Qubits with Very Lossy and Noisy Photonic Links

Exquisite quantum control has now been achieved in small ion traps, in nitrogen-vacancy centres and in superconducting qubit clusters. We can regard such a system as a universal cell with diverse technological uses from communication to large-scale computing, provided that the cell is able to network with others and overcome any noise in the interlinks. Here we show that loss-tolerant entanglement purification makes quantum computing feasible with the noisy and lossy links that are realistic today: With a modestly complex cell design, and using a surface code protocol with a network noise threshold of 13.3%, we find that interlinks which attempt entanglement at a rate of 2MHz but suffer 98% photon loss can result in kilohertz computer clock speeds (i.e. rate of high fidelity stabilizer measurements). Improved links would dramatically increase the clock speed. Our simulations employed local gates of a fidelity already achieved in ion trap devices.Comment: corrected typos, additional references, additional figur

Academic Programs in E-Commerce: Why (or Why Not), How, and What

New academic programs in electronic commerce have been created at a number of schools, while at other schools such programs have been rejected. This situation raises questions about the rationale, development process, and course requirements for e-commerce programs. This paper examines these questions by first reviewing ecommerce programs in general and then examining the case of the development of e-commerce programs at one university. The paper identifies the critical success factors in the case

Whither Wireless? Future Directions in Mobility

Wireless technology, including mobile phones, WiFi-enabled laptops, and Bluetooth-connected devices, has become entrenched in today’s society, and we can expect this technology and its mobile applications to continue to evolve in the future. But what direction will this evolution take? The purpose of this paper is to look into the future and forecast where wireless is heading, recognizing full well that making such forecasts is fraught with danger. This paper first places the rise of wireless in an historical context relative to other important information technologies of the past. It then reviews mobile issues first presented in 2002 and examines where these issues stand today. The paper next looks at other views about the future of wireless. With this background the paper makes six forecasts about the future of wireless networks, mobile phones, wireless communications standards, wireless security, ultimate commerce, and the wireless market. Drawing on these forecasts, the paper describes several research questions that could yield valuable results in the wireless arena. The paper concludes with one final forecast

Black Women in Higher Education Leadership: Examining Their Lived Experiences Utilizing Cross-Race and Cross-Gender Mentorship

Literature has suggested that mentorship is one of the most crucial and influential components for career advancement. However, Black women leaders in higher education are faced with a difficult task of selecting a mentor based on similar characteristics, which leads Black women who are seeking mentoring opportunities to select a mentor of a different race or gender. This phenomenological qualitative study was conducted to understand and describe the lived experiences of cross-race and cross-gender mentorship for a select group of Black women leaders in higher education, using Black feminist thought and intersectionality as the theoretical framework. A purposive sample of eight Black women leaders in higher education participated in in-depth interviews that were video recorded through Zoom. The collected data were transcribed and used to construct four major themes and 11 subthemes through the processes of using initial coding, in vivo coding, and descriptive coding. The major themes included the mentor’s contributions, organic connections, relational experiences, and dual role. The findings from this study imply that for this select group of Black women, cross-race only, cross-gender only, or both types of mentoring were pivotal in their professional and leadership development but were not without challenges. The results of this study could encourage individuals faced with the difficulty of identifying and selecting a mentor based on the characteristics of same-race and same-gender to seek out mentors who possess other essential qualities to aid with their career and leadership development and advancement

A Taxonomy of Collaborative Applications

This paper presents a taxonomy of collaborative applications based on the temporal, spatial, and modal dimensions of communication between members of a workgroup. The taxonomy satisfies the characteristics of being concise, sufficiently inclusive, comprehensive, and extendible. The taxonomy can be used to analyze collaborative applications and software. Common collaborative applications and representative software are summarize

Exploring the Problem-Finding and Problem-Solving Approach for Designing Organizations

An emerging problem-finding and problem-solving approach suggests that management's discovering problems to solve, opportunities to seize, and challenges to respond to, are vital to organizations. This paper explores the extent to which the problem-finding and problem-solving approach can provide a foundation for joining the capabilities, dynamic capabilities, and governance perspectives as a way to help scholars and practitioners to coherently design organizations from the perspective of design science. The problem-finding and problem-solving approach offers a unit of analysis and a set of behavioral assumptions that enable us to address open questions within the extant literature and to propose new questions in management research.
