Entanglement and scattering in quantum electrodynamics: matrix information from an entangled spectator particle

JD Fonseca, B Hiller, JB Araujo, IG da Paz, M Sampaio - Physical Review D, 2022 - APS
We consider a general quantum field relativistic scattering involving two half-spin fermions,
A and B, which are initially entangled with another fermion C that does not participate in the …

A bidirectional teleportation protocol for arbitrary two-qubit state under the supervision of a third party

BS Choudhury, A Dhara - International Journal of Theoretical Physics, 2016 - Springer
In this paper we introduce a controlled teleportation protocol for transferring arbitrary two-
qubit states bilaterally between Alice and Bob. The bidirectional teleportation protocol is …

Tensor product structures, entanglement, and particle scattering

NL Harshman, S Wickramasekara - Open Systems and Information …, 2007 - Springer

Spin-entanglement between two freely propagating electrons: Experiment and theory

D Vasilyev, FO Schumann, F Giebels, H Gollisch… - Physical Review B, 2017 - APS
Theory predicts that electron pairs, which are emitted from a crystalline surface upon impact
of spin-polarized low-energy electrons, can be spin-entangled. We quantify this …

[HTML][HTML] Multiple scattering dynamics of fermions at an isolated p-wave resonance

R Thomas, KO Roberts, E Tiesinga, ACJ Wade… - Nature …, 2016 - nature.com
The wavefunction for indistinguishable fermions is anti-symmetric under particle exchange,
which directly leads to the Pauli exclusion principle, and hence underlies the structure of …

Measuring QED cross sections via entanglement

JB Araujo, B Hiller, IG da Paz, MM Ferreira Jr… - Physical Review D, 2019 - APS
We considered a QED scattering (AB→ AB), in which B is initially entangled with a third
particle (C) that does not participate directly in the scattering. The effect of the scattering over …
