The morphology of heterostructured semiconductor nanocrystals (h-NCs) dictates the spatial distribution of charge carriers and their recombination dynamics and/or transport, which are the main performance indicators of photonic applications utilizing h-NCs. The inability to control the morphology of heterovalent III-V/II-VI h-NCs composed of heavy-metal-free elements hinders their practical use. As a case study of III-V/II-VI h-NCs, the growth control of ZnSe epilayers on InP NCs is demonstrated here. The anisotropic morphology in InP/ZnSe h-NCs is attributed to the facet-dependent energy costs for the growth of ZnSe epilayers on different facets of InP NCs, and effective chemical means for controlling the growth rates of ZnSe on different surface planes are demonstrated. Ultimately, this article capitalizes on the controlled morphology of InP/ZnSe h-NCs to expand their photophysical characteristics from stable and pure emission to environment-sensitive one, which will facilitate their use in a variety of photonic applications.

Abstract The emergence of state-sanctioned worker-run social cooperatives as a government-certified social enterprise model in South Korea, functioning simultaneously as worker cooperatives, represents an evolutionary shift in the country’s cooperative movement. Enabled by the enactment of important regulatory frameworks, including the 2006 Social Enterprise Promotion Act and the 2012 Framework Act on Cooperatives, these novel hybrid organizational forms reside at the intersection of traditional worker cooperative and government-certified social enterprise organizational forms. This study uses Q-methodology to assess the perspectives of worker-members, revealing insights into the organizational identities of these cooperatives. Three distinct perspectives emerge: “Pragmatic and Empowered Participative Work-Integrated Social Catalysts,” “Public Sector-Backed, Internally Marginalized Social Contributors,” and “(Partially) Disillusioned Network-Centric Social Contributors.” These perspectives underline the diversity in worker-members’ perspectives on these organizational forms. While some worker-members are content, others express discontent, suggesting the existence of tensions between traditional cooperative principles and these novel state-sanctioned social economy organizations. These findings provide insights into the interface between public sector social economy organization policies and traditional cooperative ideals.

We propose Shuttling-based Distributed Quantum Computing (SDQC), a hybrid architecture that combines the strengths of physical qubit shuttling and distributed quantum computing to enable scalable trapped-ion quantum computing. SDQC performs non-local quantum operations by distributing entangled ion qubits via deterministic shuttling, combining the high-fidelity and deterministic operations of shuttling-based architectures with the parallelism and pipelining advantages of distributed quantum computing. We present (1) a practical architecture incorporating quantum error correction (QEC), (2) pipelining strategies to exploit parallelism in entanglement distribution and measurement, and (3) a performance evaluation in terms of logical error rate and clock speed. For a 256-bit elliptic-curve discrete logarithm problem (ECDLP) instance, which requires 2,871 logical qubits at code distance 13, SDQC achieves a logical error rate which is $1.20_{-0.45}^{+0.94}\times 10^{-8}$ of Photonic DQC error rate and $3.79_{-2.84}^{+5.09}\times 10^{-3}$ of Quantum Charge-Coupled Device (QCCD) error rate, while providing 2.82 times faster logical clock speed than QCCD.

An elementary review on principles of qubits and their prospects for quantum computing is provided. Due to its rapid development, quantum computing has attracted considerable attention as a core technology for the next generation and has demonstrated its potential in simulations of exotic materials, molecular structures, and theoretical computer science. To achieve fully error-corrected quantum computers, building a logical qubit from multiple physical qubits is crucial. The number of physical qubits needed depends on their error rates, making error reduction in physical qubits vital. Numerous efforts to reduce errors are ongoing in both existing and emerging quantum systems. Here, the principle and development of qubits, as well as the current status of the field, are reviewed to provide information to researchers from various fields and give insights into this promising technology.

We report the direct measurement of isotope shifts of the barium $6s^2$ ${}^1{S}_0\text{–}5d6p^3{D}_1^{\mathrm{o}}$ 413-nm electric quadrupole transition, which is utilized for efficient barium ion trapping via photoionization using a single coherent light source. The measured isotope shifts relative to ${}^{138}\mathrm{Ba}$ are $392.9\text{ifmmode}\pm \text{else}\text{textpm}\text{fi}0.9\mathrm{MHz}$, $178.1\text{ifmmode}\pm \text{else}\text{textpm}\text{fi}0.8\mathrm{MHz}$, $401.4\text{ifmmode}\pm \text{else}\text{textpm}\text{fi}1.2\mathrm{MHz}$, and $124.3\text{ifmmode}\pm \text{else}\text{textpm}\text{fi}1.3\mathrm{MHz}$ for isotopes with atomic numbers 137, 136, 135, and 134, respectively. We verify the measured isotopes with King plot analysis and compare the result with the formerly known shifts inferred from previous studies on neighboring transitions. The results can be used for efficient isotope selective loading of low-abundant barium ions, while careful suppression of line broadening is required for successful isotopic selectivity.
