Physics and Architecture of Spin-Based Quantum Computing with Electrons on the Surface of Liquid Helium

基于自旋的液氦表面电子量子计算：物理和计算机体系结构这个项目是一项跨学科的努力，旨在研究一种新的实现方法的物理和结构，该实现方法使用液氦表面的电子自旋作为量子比特。两个主要研究部分是操纵氦上电子的基本物理的实验研究，以及最能利用基于自旋的系统的体系结构和应用的开发：可扩展，但包括保持电子良好分离和避免磁扰动等约束。这些活动之间的紧密耦合一方面指导物理和设备实验，另一方面确保为建筑设计开发逼真的模型。人们正在使用门进行实验，就像那些电荷耦合成像仪中的门一样，以控制光刻定义的通道中持有的超流氦上的电子。这种并行结构是许多基于自旋的实现的原型，体系结构工作的一个特别焦点是针对某些问题的基于经典门阵列的加速器的设计。该项目为从事这方面工作的研究生和博士后提供了广泛的培训。他们从事并接触到广泛的研究，包括量子物理、半导体技术、低温物理、算法和计算机体系结构。该项目为普林斯顿和其他学校的本科生提供了丰富的教育机会。

Spin-Based Quantum Computing Using Electrons on the Surface of Liquid Helium: Physics and Computer ArchitectureThis project is an interdisciplinary effort to investigate the physics and the architecture of a new implementation which uses the spin of electrons on the surface of liquid helium as the qubits.The two major research components are the experimental investigation of the underlying physics of manipulating electrons on helium, and the development of architectures and applications that are best be able to utilize the spin-based system: scalable, but including such constrains as maintaining the electrons well separated and avoiding magnetic perturbations. A tight coupling between these activities guides the physics and device experiments on the one hand, and ensures the development of realistic models for the architecture designs on the other. Experiments are being conducted using gates, much like those in charge-coupled imagers, to control electrons on superfluid helium held in lithographically defined channels. Such parallel structures are prototypical of many spin-based implementations, and a particular focus of the architecture effort is on designs which follow from classical gate-array based accelerators for certain problems.This project gives a broad training to the graduate student and postdoctoral fellow working on it. They conduct and are exposed to a wide range of research, including quantum physics, semiconductor technology, low-temperature physics, algorithms and computer architecture. The project provides a wealth of educational opportunities for undergraduates, both within Princeton and from other schools.
