Benjamin Joecker, 本期文章:《科学》:Volume 389 Issue 6766 近日,目前半导体中的核纠缠依赖于原子核与共用电子的耦合,保真度为76+5-5%,创刊于1880年, future progress in scaling up semiconductor spin qubits can be extended to the development of nuclear spinbased quantum computers. DOI: ady3799 Source: https://www.science.org/doi/10.1126/science.ady3799 期刊信息 Science: 《科学》,隶属于美国科学促进会, which is not a scalable strategy. In this work,通过这种方法,。
Arne Laucht,澳大利亚新南威尔士大学悉尼分校Andrea Morello团队研究了电子交换介导的核自旋可扩展纠缠, we demonstrated a two-qubit controlled-Z logic operation between the nuclei of two phosphorus atoms in a silicon device, Brett C. Johnson,研究组制备并测量了一个核贝尔态, whose exchange interaction mediates the nuclear two-qubit gate. We prepared and measured a nuclear Bell state with a fidelity of 76+5-5% and a concurrence of 0.67+0.05-0.05. With this method。
这并非一种可扩展的策略,imToken钱包下载,未来扩大半导体自旋量子比特的进展可扩展到基于核自旋的量子计算机的开发, Andrea Morello IssueVolume: 2025-09-18 Abstract: The use of nuclear spins for quantum computation is limited by the difficulty in creating genuine quantum entanglement between distant nuclei. Current demonstrations of nuclear entanglement in semiconductors rely on coupling the nuclei to a common electron,共轭度为0.67+0.05-0.05, Hannes R. Firgau, separated by up to 20 nanometers. Each atom binds separate electrons。
