摘要:

全面研究了力检测单自旋磁共振测量概念与原子空间分辨率。该方法是基于静电力检测自旋选择规则控制的两个电隔离的顺磁状态之间的单电子隧穿。单自旋磁共振检测是可能的,通过测量力检测隧穿电荷噪声和关闭自旋共振。这种电荷噪声的模拟结果,基于隧道和自旋物理的物理模型,直接比较测得的AFM系统噪声。结果表明,该方法可以在室温下对电隔离量子比特态进行具有原子空间分辨率的单自旋测量。

英文摘要:

A comprehensive study of a force detected single-spin magnetic resonance measurement concept with atomic spatial resolution is presented. The method is based upon electrostatic force detection of spin-selection rule controlled single-electron tunneling between two electrically isolated paramagnetic states. Single spin magnetic resonance detection is possible by measuring the force detected tunneling charge noise on and off spin resonance. Simulation results of this charge noise, based upon physical models of the tunneling and spin physics, are directly compared to measured AFM system noise. The results show that the approach could provide single spin measurement of electrically isolated qubit states with atomic spatial resolution at room temperature.
