项目摘要

Serge Haroche and Dave Wineland were awarded the 2012 Nobel prize in physics for developing experimental methods for controlling and manipulating individual quantum systems. The groundwork that they laid has led to spectacular progress in the past two decades on the development of increasingly sophisticated methods for achieving exquisite control over single quantum systems. This has coincided with an increasing (academic and commercial) interest worldwide on the development of novel computing, communication and sensing platforms that exploit the surprising effects underlying quantum systems, in particular superposition and entanglement, and have fueled the second quantum revolution.As our understanding and control of individual quantum systems grows, there is an ever-present need for the development of novel experimental methods that provide greater control and sensitivity in manipulating and reading out individual quantum systems. This project outlines the use of one such platform, based on exploiting the surface electric and magnetic fields in piezoelectric microresonators, for achieving greater sensitivity in the control and readout of nanoscale spin systems. The sensitivity enhancement comes out from confining the fields to deeply subwavelength volumes in high quality factor cavities, an effect that is well known in cavity quantum electrodynamics. While this proposal is aimed at proving the underlying principles and developing the novel experimental platform, we envision this work will revolutionize the way we control and manipulate spin systems for a wide variety of applications, ranging from performing electron spin resonance on nanoscale biological samples to enabling electrical readout of single spins for spin based quantum information processing.

Serge Haroche和Dave Wineland因开发控制和操纵单个量子系统的实验方法而获得2012年诺贝尔物理学奖。在过去的二十年里，他们奠定的基础导致了在开发越来越复杂的方法以实现对单量子系统的精细控制方面的惊人进展。与此同时，随着我们对单个量子系统的理解和控制的增长，世界范围内（学术和商业）对开发新型计算、通信和传感平台的兴趣越来越大，这些平台利用了量子系统的惊人效应，特别是叠加和纠缠，并推动了第二次量子革命。一直需要开发在操纵和阅读单个量子系统时提供更大控制和灵敏度的新实验方法。该项目概述了一个这样的平台的使用，基于利用压电微谐振器中的表面电场和磁场，以实现更高的灵敏度，在控制和读出的纳米级自旋系统。灵敏度的增强来自于将场限制在高品质因子腔中的深亚波长体积，这种效应在腔量子电动力学中是众所周知的。虽然这项提议的目的是证明基本原理和开发新的实验平台，但我们设想这项工作将彻底改变我们控制和操纵自旋系统的方式，用于各种各样的应用，从在纳米级生物样品上进行电子自旋共振，到使单自旋的电读出用于基于自旋的量子信息处理。
