Fabrication techniques have progressed to the stage where it is possible to manufacture superconducting circuits and mechanical devices with feature sizes of a few billionths of a meter - the nanoscale. At these length scales devices must be described by the laws of quantum physics. These quantum effects can be used to dramatically aid in a number of tasks in information processing, communication, and metrology. At present, a realistic, complete model of quantum measurement in these systems is lacking. This project aims to fill this gap in our knowledge. The resultant theory will be applied to study how quantum effects in nanotechnology can be exploited to aid in applications such as information processing and metrology. It is believed that these applications will act as an enabling technology for future experiments in basic science.The proposed programme stands at the boundary between two key EPSRC research priorities - quantum information processing and nanoscale research.The research will be undertaken at the Quantum Information and Quantum Optics Theory group (Imperial College), taking advantage of the existing quantum information and quantum measurement expertise in the group. A vital part of this project will be close interaction with experimentalists at the National Physical Laboratory.

制造技术已经发展到可以制造特征尺寸为几十亿分之一米（纳米级）的超导电路和机械设备的阶段。在这些长度尺度上，器件必须由量子物理定律来描述。这些量子效应可用于极大地帮助信息处理，通信和计量学中的许多任务。目前，在这些系统中缺乏一个现实的，完整的量子测量模型。这个项目旨在填补我们知识上的这一空白。由此产生的理论将被应用于研究如何利用纳米技术中的量子效应来帮助信息处理和计量学等应用。这些应用相信会为未来的基础科学实验提供一项可行的技术。拟议的计划介于EPSRC的两个主要研究重点-量子信息处理和纳米尺度研究之间。研究将在量子信息和量子光学理论组进行（帝国理工学院），利用该集团现有的量子信息和量子测量专业知识。该项目的一个重要部分将是与国家物理实验室的实验人员密切互动。
