微软量子赌局:一场耗资10亿的“猫鼠游戏”,谁能证明马约拉纳的存在?
Sou Hu Cai Jing· 2025-10-03 06:08
原文发表于《科技导报》2025年第16期科技新闻-深度报道 此项更正同样不大可能平息围绕微软赞助的马约拉纳研究的广泛争议,微软已向该领域投入逾10亿美元资金。2025年2月,当微软宣布其号称全球首款基 于马约拉纳的量子处理芯片时,不仅遭到独立专家的质疑,更引来一群坚定批评者的彻底蔑视。美国马里兰大学凝聚态理论家Jay Sau表示:"这是科学、 社交媒体和企业相互交织下过度狂热的产物。毫无疑问,所有这些争议已让'马约拉纳'这个词笼罩在有毒的阴云之中。" 与必须设置为0或1的经典比特不同,量子比特可以处于0和1状态共存的"叠加态"。理论上,利用这种特性的设备可以在某些领域(如密码破译和高级化学 模拟)超越经典计算机。 但量子比特本身非常脆弱,任何微小干扰都可能使其精心构建的叠加态坍缩。这正是微软等机构致力于开发拓扑量子比特的原因,该技术通过空间分布量 子态来抵御局部噪声干扰。例如,若研究人员能在超细纳米线的原子晶格内以特定方式排列电子和带正电的"空穴",单个电子会呈现被撕裂成两半的状 态,并分别向导线两端移动。这种分裂效应应能使这些半电子量子比特表现出自身反粒子的特性(该特性以20世纪初意大利物理学家Ettore ...

新型量子纠错码开发成功,性能非常接近哈希界限
Ke Ji Ri Bao· 2025-09-30 07:55
Core Insights - The Tokyo University of Science team has made significant advancements in quantum error correction technology by developing an efficient and scalable quantum Low-Density Parity-Check (LDPC) error-correcting code that maintains high stability in systems with hundreds of thousands of logical qubits, approaching theoretical limits [1][2] - This breakthrough provides crucial technical support for achieving large-scale fault-tolerant quantum computing, potentially accelerating practical applications in quantum chemistry, cryptanalysis, and complex optimization [1] Group 1 - The current quantum computers can manipulate dozens of qubits, but solving real-world problems often requires millions of stable and reliable logical qubits [1] - Existing quantum error correction methods generally suffer from high resource consumption and low efficiency, requiring many physical qubits to encode a small number of logical qubits, which severely limits system scalability [1] - Many existing error correction codes have low coding rates and limited performance improvement potential, with significant gaps remaining from the theoretical optimal error correction limit known as the hashing bound [1] Group 2 - The team successfully overcame these challenges by proposing a new construction method that designs prototype LDPC codes with excellent error correction characteristics and introduces affine arrangement-based techniques to enhance code structure diversity [2] - Unlike traditional LDPC codes defined over binary finite fields, the new approach uses non-binary finite fields, allowing each encoding unit to carry more information and thus improving overall error correction capability [2] - The team transformed these prototype codes into a CSS-type quantum error correction code and developed an efficient joint decoding strategy that can simultaneously handle bit-flip and phase-flip errors, unlike most previous methods that could only correct one type at a time [2] Group 3 - Through large-scale numerical simulations, the new error correction code achieves a bit error rate of 10^-4 in systems with hundreds of thousands of logical qubits, with performance very close to the hashing bound [2] - Importantly, the computational complexity required for decoding is proportional to the number of physical qubits, meaning that as system size increases, the resource overhead grows linearly, indicating good engineering feasibility [2]
