Silicon photonics interfaced with microelectronics for integrated photonic quantum technologies: a new era in advanced quantum computers and quantum communications?

This review discusses the potential of silicon photonics combined with CMOS electronics to advance quantum computing and communication, focusing on improvements in homodyne detectors and integration methods. The authors suggest this approach could lead to faster data transfer and more powerful quantum technologies.

High entropy spinel oxide nanoparticles for superior lithiation-delithiation performance

Researchers synthesized high-entropy spinel oxide nanoparticles (HESOs) with non-equimolar Cr, Mn, Fe, Co, and Ni for use as a lithium-ion battery anode. The HESO exhibited a high reversible capacity (1235 mAh g⁻¹), excellent rate capability (500 mAh g⁻¹ at 2000 mA g⁻¹), and good cycling stability (90% capacity retention after 200 cycles) due to entropy stabilization and the presence of oxygen vacancies.

A retrospective on lithium-ion batteries

This comment reviews key milestones in the development of lithium-ion batteries, from early work with lithium metal and titanium disulfide to the adoption of graphite anodes, lithium cobalt oxide cathodes, and stable electrolytes. The authors highlight the importance of incremental progress, mechanistic understanding, and cross-disciplinary research in achieving these breakthroughs.
