Two-site reduced density matrix from one-and two-particle Green's functions
Strongly correlated electron systems are challenging to calculate, and entanglement in such
systems is not widely analyzed. We present an approach that can be used as a …

General teleportation channel in Fermionic Quantum Theory
S Khan, R Jehadeesan, S Ghosh - arXiv preprint arXiv:2312.04240, 2023 - arxiv.org
Quantum Teleportation is a very useful scheme for transferring quantum information. Given
that the quantum information is encoded in a state of a system of distinguishable particles …

Orbital-free quasidensity functional theory
CL Benavides-Riveros - Physical Review Research, 2024 - APS
We develop an orbital-free functional framework to compute one-body quasiprobabilities for
both fermionic and bosonic systems. Since the key variable is a quasidensity, this theory …

Topological correlation in anyonic states constrained by anyonic superselection rules
CQ Xu, DL Zhou - Physical Review A, 2023 - APS
An anyonic system not only has potential applications in the construction of topological
quantum computers but also presents a unique property known as topological entanglement …
