电子高度激发（Rydberg）原子经历类似于复杂分子中发现的福斯特过程的量子状态变化相互作用，提供了一个模型系统来研究受控环境影响下偶极介导的能量传输的性质。我们展示了一种无损成像方法来监测迁移的电子激发与高的时间和空间分辨率，使用电磁感应透明的背景气体作为放大器。观测到的电子量子态的连续空间投影决定了能量输运的多体动力学。
Electronically highly excited (Rydberg) atoms experience quantum state-changing interactions similar to Forster processes found in complex molecules, offering a model system to study the nature of dipole-mediated energy transport under the influence of a controlled environment. We demonstrate a nondestructive imaging method to monitor the migration of electronic excitations with high time and spatial resolution, using electromagnetically induced transparency on a background gas acting as an amplifier. The continuous spatial projection of the electronic quantum state under observation determines the many-body dynamics of the energy transport.
