Learning high-dimensional quantum entanglement through physics-guided neural networks
Yang Xu, Hao Zhang, Wenwen Zhang +4
High-gain spontaneous parametric down-conversion (SPDC) produces bright squeezed vacuum with rich high-dimensional entanglement, but its output is inherently multimodal and non-per…
TENSO: Software Package for Numerically Exact Open Quantum Dynamics Based on Efficient Tree Tensor Network Decomposition of the Hierarchical Equations of Motion
Juan C. Rodriguez-Betancourt, Michelle C. Anderson, Luchang Niu +2
TENSO is a versatile and powerful open-source software package for numerically exact simulations of the dynamics of quantum systems immersed in structured thermal environments. It…
Optimal propagation distance for maximal biphoton entanglement through the weakly turbulent atmosphere
Luchang Niu, Saleem Iqbal, Yang Xu +1
Understanding the influence of atmospheric turbulence on the propagation of entangled biphoton states is essential for free-space quantum communication protocols. Using the extende…
Universal and Tunable Sudden Freezing of Entanglement Volume
Luchang Niu, Joseph H. Eberly
In a system where two identical two-level atoms interact with their common one-mode cavity field, it is shown that entanglement can become abruptly frozen in time, remaining at a c…
