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荣获 2012 年诺贝尔物理学奖。他们奠定的基础在过去二十年中在开发日益复杂的方法以实现对单量子系统的精确控制方面取得了惊人的进展。与此同时，全世界（学术和商业）对开发新型计算、通信和传感平台的兴趣日益浓厚，这些平台利用了量子系统背后的惊人效应，特别是叠加和纠缠，并推动了第二次量子革命。据我们了解随着对单个量子系统的控制的不断增长，人们始终需要开发新颖的实验方法，以在操纵和读取单个量子系统方面提供更好的控制和灵敏度。该项目概述了基于利用压电微谐振器中的表面电场和磁场的此类平台的使用，以在纳米级自旋系统的控制和读出中实现更高的灵敏度。灵敏度的增强来自于将场限制在高质量因子腔中的深亚波长体积内，这种效应在腔量子电动力学中是众所周知的。虽然该提案旨在证明基本原理并开发新颖的实验平台，但我们预计这项工作将彻底改变我们控制和操纵自旋系统的方式，以实现各种应用，从在纳米级生物样品上执行电子自旋共振到实现用于基于自旋的量子信息处理的单自旋的电读出。
