项目摘要

Non-technical Abstract:The team aims to make topological superconducting nanowires as the building blocks of new quantum computers that are more robust and energy efficient than current quantum computers. Nanodevices based on these nanowires are used to demonstrate the basic rules for quantum computations. The superconducting nanowires are made of indium doped tin telluride, and are expected to alleviate some of the challenging technical constraints imposed on a competing system, a semiconducting nanowire with large spin orbit coupling. A portion of the research is included in the undergraduate and graduate physics curriculum to inspire and encourage students to pursue research. Undergraduate students are involved in the project through senior research projects, REU programs, and summer research internships. Collaboration between Yale University and the University of Maryland at College Park provide broader networking opportunities to graduate students. Technical Abstract:The team aims to demonstrate braiding anyon world lines using indium-doped tin telluride (SnTe) topological superconductor nanowires and nanowire junctions. Indium-doped SnTe - SnTe junction nanowires are synthesized via a growth method that adapts the vapor-liquid-solid growth mechanism. Superconducting topological nanowires eliminate the need for superconducting contacts. Nanodevices using the heterojunction nanowires are be fabricated to demonstrate the signatures of Majorana fermions (MFs) at the junctions and perform fusion and braiding operations. A half quantum flux magnetic field is to be applied parallel to the nanowire to ensure the topological superconducting phase while small additional local magnetic fields are to be used to generate, manipulate, and fuse MFs. Quantum dot devices on the nanowire are used to read out the parity through the parity-to-charge conversion. The use of magnetic fields, instead of electric gating, combined with relaxed conditions for the placement of chemical potentials, represents technical advantages for this system.
非技术摘要:该团队的目标是制造拓扑超导纳米线,作为新量子计算机的构建块,这种计算机比目前的量子计算机更强大、更节能。基于这些纳米线的纳米器件被用来演示量子计算的基本规则。超导纳米线是由掺铟的碲化锡制成的,预计将缓解竞争系统施加的一些具有挑战性的技术限制,这是一种具有大自旋轨道耦合的半导体纳米线。研究的一部分包括在本科生和研究生的物理课程中,以激励和鼓励学生从事研究。本科生通过高级研究项目、REU项目和暑期研究实习参与该项目。耶鲁大学和马里兰大学在学院公园的合作为研究生提供了更广泛的网络机会。技术摘要:该团队的目标是演示使用掺铟碲化锡(SNTE)拓扑超导体纳米线和纳米线结来编织任意子世界线。采用气-液-固生长机制制备了掺铟SnTe-SnTe结纳米线。超导拓扑纳米线消除了对超导接触的需要。使用异质结纳米线的纳米器件被用来展示结处的Majorana费米子(MFS)的特征,并执行融合和编织操作。半量子磁通磁场将平行于纳米线,以确保拓扑超导相,同时将使用较小的附加局部磁场来产生、操纵和引信MFS。纳米线上的量子点装置通过奇偶到电荷的转换来读出奇偶。使用磁场,而不是电门,结合宽松的化学电势放置条件,代表了该系统的技术优势。
