overview of the rapidly advancing field of quantum technology, focusing particularly on global competition, technological advancements, and strategic policy efforts. Multiple documents detail the intense geopolitical race for quantum supremacy between major powers like the United States, China, and the European Union, highlighting China's massive state investment versus the substantial private sector funding in the U.S. Significant technical breakthroughs are covered, including Microsoft's development of the error-resistant Majorana 1 chip and Google's creation of new non-equilibrium quantum phases, alongside the critical importance of quantum error correction (QEC) for creating scalable, useful quantum computers. Furthermore, the sources outline national and international strategies—such as the EU's Quantum Europe Strategy and the US National Quantum Initiative—to foster workforce development, establish secure quantum networks and testbeds, and deploy post-quantum encryption standards to mitigate future cryptographic threats. Investment trends reveal that quantum computing dominates venture funding, signaling growing market confidence in the near-term commercial readiness of this transformative technology.
