论文摘要
我们提出了一种连续的可变量子状态层析成像方案，该方案是由于原子或分子的电离而通过吸收极端紫外脉冲而导致的。我们的协议是根据FANO共振附近从氦气和氩气中弹出的光电子量子状态的直接计算基准测试的。在后一种情况下，由于自旋轨道分裂而导致的蒸馏液离子 - 光珠纠缠。这为对超快时间尺度上量子相干性和纠缠特性的调查开辟了新的途径。
We propose a continuous variable quantum state tomography protocol of electrons which result from the ionization of atoms or molecules by the absorption of extreme ultraviolet light pulses. Our protocol is benchmarked against a direct calculation of the quantum state of photoelectrons ejected from helium and argon in the vicinity of a Fano resonance. In the latter case, we furthermore distill ion-photoelectron entanglement due to spin-orbit splitting. This opens new routes towards the investigation of quantum coherence and entanglement properties on the ultrafast timescale.
