US and Iran Sign Memorandum of Understanding - Reports

The upcoming memorandum of understanding between the United States and Iran was discussed by Presidents Vladimir Putin of Russia and Donald Trump of the United States during their phone call.

Trump said that an agreement is close and that he expects the results of the difficult but ultimately successful negotiations to be announced as early as today. Separate preparatory meetings with representatives of Iran and the United States will be held in the Qatari capital of Doha.

Earlier, US President Donald Trump and Iranian Deputy Foreign Minister Kazem Gharibabadi confirmed the completion of a memorandum of understanding, which is to be signed in Switzerland on June 19. Preparatory meetings with each side will be held in Doha this week ahead of the official signing of the agreement in Switzerland this Friday and the start of technical negotiations, the Channel reported, citing a diplomatic source familiar with the situation.

The details of the memorandum of understanding signed by the United States and Iran will be made public within the next two days, media reported on Monday, citing a senior US official. US Vice President JD Vance further said that Washington hopes to release the content of the agreement sometime this week.

China mass produces silicon-28 isotopes with over 99.99% enrichment for quantum chips

Chinese scientists have made a major breakthrough in the field of stable Isotope enrichment, successfully realising mass production of Silicon-28 Isotopes with an abundance exceeding 99.99 percent for the first time.

The breakthrough was developed by the Research Institute of Physical and Chemical Engineering of Nuclear Industry (Ipce), under the Cnnc subsidiary China Nuclear Energy Industry Co. The achievement marks an important step forward in building an independent, controllable, and efficient stable Isotope industrial system in China, with the product's key indicators reaching internationally advanced levels.

Silicon-28 is considered a critical material for silicon-based quantum chips, which are widely seen as one of the most promising pathways toward scalable quantum computing. as a stable Isotope of silicon with zero nuclear spin, it can significantly reduce environmental noise that interferes with quantum operations, earning it the nickname "the world's purest silicon." The breakthrough is expected to provide strong support for the independent development of core materials for silicon-based quantum computing, while also advancing frontier fields including next-generation semiconductor manufacturing, high-end navigation systems, and precision Metrology.

The advancement will facilitate the independent development of core materials for silicon-based quantum computing in China, as well as bolster the development of advanced semiconductor manufacturing processes, high-end navigation and measurement benchmarks.

OpenAI wins dismissal of trade secret lawsuit by Musk's xAI

A federal judge has dismissed a lawsuit filed by Elon Musk's artificial intelligence company xAI that accused rival Sam Altman's OpenAI of stealing its trade secrets.

U.S. District Judge Rita LIN in San Francisco said xAI failed to show that OpenAI induced former xAI engineer Xuechen Li to Misappropriate trade secrets or that Li disclosed xAI trade secrets in a presentation he delivered while OpenAI was recruiting him.

LIN dismissed the case with prejudice, saying it would be "futile" for xAI to continue. Originally filed last September, the lawsuit claimed that former xAI employees took confidential information, including source code related to the Grok chatbot, when they left for new jobs at OpenAI.

The xAI business is part of Musk's rocket, satellite and AI company SpaceX. Lawyers for xAI did not immediately respond to requests for comment.
