Quantum entanglement during single-cycle nonsequential ionization
Daniel Younis, Songbo Xie, Joseph H. Eberly
In order to elucidate the correlated motion of atomic electrons, we investigate the attosecond-scale dynamics of their entanglement arising due to nonsequential ionization driven b…
Multipartite Entanglement: A Journey Through Geometry
Songbo Xie, Daniel Younis, Yuhan Mei +1
Genuine multipartite entanglement is crucial for quantum information and related technologies but quantifying it has been a long-standing challenge. Most proposed measures do not m…
Strong-Field Nonsequential Double Photoionization Using Virtual Detector Theory with Path Summation
Daniel Younis, Joseph H. Eberly
We present an ab initio study of the nonsequential strong-field ionization dynamics of a model two-electron atom with helium character. Single- and double-ionization events are cha…
Unexpected Robustness of Multipartite Entanglement against Sudden Death from Spontaneous Emission
Songbo Xie, Daniel Younis, Joseph H. Eberly
Entanglement is known to decay even in isolated systems, an effect attributed to spontaneous emission. This fragility of entanglement can be exacerbated by entanglement sudden deat…
