IBM，要造最强量子计算机

Core Viewpoint - IBM plans to build the world's first large-scale fault-tolerant quantum computer, named IBM Quantum Starling, by the end of this century, which will have a computing power 20,000 times greater than current quantum computers [2]. Group 1: Quantum Computing Developments - Quantum computers store information as quantum bits (qubits), which can exist in both "0" and "1" states simultaneously, allowing for more powerful computations compared to classical computers [3]. - A major challenge in quantum computing is the susceptibility of qubits to errors caused by "noise," which are small environmental interferences that can disrupt their quantum state [3]. Group 2: IBM's Roadmap and Collaborations - IBM's confidence in achieving a fault-tolerant quantum computer by 2029 is based on advancements in error reduction methods, specifically the "quantum low-density parity-check" (qLDPC) code, and real-time error correction techniques using classical computing [4]. - IBM is collaborating with the quantum startup SEEQC as part of a U.S. Defense Advanced Research Projects Agency (DARPA) quantum benchmarking program to assess the scalability of quantum operations [4]. Group 3: Market Implications and Industry Reactions - IBM aims to stimulate developer interest in creating quantum algorithms, which are crucial for realizing returns on investment in quantum computing [5]. - Analysts express skepticism about how IBM's breakthroughs will translate into tangible commercial value, noting that the transformative potential of fault-tolerant quantum computers remains speculative [5]. - The comprehensive nature of IBM's plans for building a fault-tolerant quantum computer is noteworthy and should alert businesses and the tech community to the rapid advancements in quantum computing [6].
