心智观察所：量子计算机很可能永远不会成功

Core Viewpoint - A recent YouTube video titled "Why Quantum Computers May Never Succeed" has garnered significant attention, with over 190,000 views, 10,000 likes, and 1,400 comments, highlighting skepticism towards the future of quantum computing [1][3]. Group 1: Video Content and Creator - The video was released on the last day of 2025, amidst ongoing discussions about quantum computing, casting uncertainty on its future development [3]. - The creator, Sabine Hossenfelder, is a theoretical physicist known for her critical stance on technological optimism and her emphasis on the limitations imposed by physical laws and societal factors on technological advancements [3][4]. Group 2: Challenges Facing Quantum Computing - Quantum computing faces three major challenges: 1. The physical foundations of quantum computing remain unverified, as large-scale, deeply entangled quantum systems have not been directly observed or tested [4][5]. 2. Quantum computing has not yet demonstrated a universal leap in computational power, as the assumptions underlying its potential for exponential speedup are being questioned [6][7]. 3. The theoretical framework supporting quantum computing may require revision, as the standard form of quantum mechanics might not hold in extremely complex systems [8][9]. Group 3: Specific Theoretical Concerns - There are concerns that as physical systems increase in size, quantum effects may diminish, and the reasons for this phenomenon remain unresolved [5]. - If the underlying assumptions about quantum states and their manipulation are flawed, the anticipated advantages of quantum algorithms may only apply to small-scale or specific problems, limiting their practical applicability [6][7]. - The potential for quantum computing to achieve significant computational advantages is contingent upon the verification of its physical principles, the scalability of its algorithms, and the validity of its theoretical foundations [9].
