Summary: A new spectroscopic method was developed to characterize the coupling of two microwave-photon-coupled semiconductor qubits via a high-impedance resonator, revealing distinctive geometric patterns that align with simulation results. This method could be a key component in quickly characterizing collective properties of multiple cavity QED-coupled qubits.

Summary: In recent decades, additive manufacturing (AM) has emerged as a reliable tool for prototyping and low-volume production. The market share of AM products has rapidly increased due to the ability to create more complex parts compared to traditional manufacturing technologies. Biopolymers have also gained popularity in AM as recyclability and biocompatibility have become important factors in material selection. This article provides an overview of AM with advanced biopolymers in various fields and discusses different AM technologies, biopolymer usage, part fabrication strategies, and influential parameters of these technologies. The potential of achieving complex parts using AM is explored, with considerations for manufacturable features, layer thickness, production accuracy, material properties, and part strength. Additionally, future trends in 4D additive manufacturing for biopolymers are discussed.

Summary: A key challenge in semiconductor quantum-dot charge qubits is achieving long-range qubit coupling and performing high-fidelity gates. This study presents a different type of charge qubit formed by an electron confined in a triple-quantum-dot system, enabling single and two-qubit gates in specific detuning sweet spots. The study also proposes a form of long-range dipolar coupling between the charge qubit and superconducting resonator, allowing for entangling gates in both dispersive and resonant regimes.

Summary: In semiconductor manufacturing, manufacturing equipment is managed through quality control, which checks the shape of processed features to ensure they meet specifications. If the shape is not within specifications, recipe parameters are adjusted. The calculation method for these parameters relies on individual engineers' expertise, leading to quality control difficulties. To overcome this problem, an automatic calculation method for optimal recipe parameters was developed using Advanced Process Control (APC) system with the stacking model method. The system also includes a comparison of two gap scoring methods and optimization of recipe parameter exploration methods through on-site demonstrations.

Summary: Additive manufacturing allows for fast production of polymer gears directly from a 3D model, with the ability to easily replace failed gears using different materials. The mechanical and thermal characteristics of these gears depend on the selected manufacturing parameters and material. This research experimentally investigates the influence of the most important manufacturing parameter, infill percentage, on the failure types and service life of additive manufactured nylon gears.

Summary: This study investigates the hot working behavior of Ti-6Al-4 V samples produced using DEO and SLM methods, highlighting differences in flow stress and microstructure evolution between conventional and AM materials. A model is proposed to predict flow stresses and microstructure evolution in Ti-6Al-4 V specimens with conventional and AM microstructures, which takes the spatial arrangement into account. These findings can be utilized to design new process chains for single-stage net-shape forging of Ti-6Al-4 V parts with reduced forming forces and improved mechanical properties.

Summary: Quantum computation (QC) is a highly challenging quantum technology that could revolutionize data computation by surpassing classical supercomputers in specific applications. To avoid failures, quantum error correction codes are necessary to limit and correct errors. Implementing the surface code requires millions of highly-coherent qubits arranged in a two-dimensional array. Metal-oxide-semiconductor technology is an attractive option for manufacturing such large numbers of high-quality devices. This review focuses on modeling, fabrication aspects, experimental figures of merit, and potential applications of qubits in silicon devices, as well as the role of start-ups and companies in the silicon-based QC era.

Summary: This research reveals that temperature fluctuations can lead to the generation of 1/f-like noise power spectral density, even from a single two-level system. Furthermore, a distribution of fluctuators modifies the Dutta-Horn relation. Additionally, recent experimental data suggests that charge noise in silicon quantum dot qubits can be explained by as few as two two-level fluctuators, with the consideration of sub-bath size improving the fit quality.

Summary: Research suggests that incumbents can successfully divert potential entrants from their submarkets to other submarkets within the same industry by strategically investing to decrease the expected profits of the target submarket. This is important for sustaining incumbents' profits. New entrants will still enter the industry, but they will settle in different submarkets.
