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

使用液氦表面上的电子进行基于自旋的量子计算：物理学与计算机体系结构本项目是一个跨学科的研究项目，旨在研究一种新的实现方式的物理学和体系结构，该实现方式使用液氦表面上的电子自旋作为量子比特。两个主要的研究组成部分是实验研究在氦上操纵电子的基本物理学，以及最好能够利用基于自旋的系统的架构和应用的开发：可扩展的，但包括诸如保持电子良好分离和避免磁扰动之类的约束。 这些活动之间的紧密耦合一方面指导物理和器件实验，另一方面确保为架构设计开发逼真的模型。实验正在进行使用门，很像那些在电荷耦合成像器，以控制电子超流氦举行光刻定义的通道。这种并行结构是许多基于自旋的实现的原型，并且架构工作的特别重点是针对某些问题遵循经典的基于门阵列的加速器的设计。该项目为从事该项目的研究生和博士后研究员提供了广泛的培训。他们进行并接触到广泛的研究，包括量子物理，半导体技术，低温物理，算法和计算机架构。 该项目为普林斯顿大学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.
