Bell Test of Photons from Electron-Positron Annihilation via POVM-based Compton Polarimetry
Jack Clarke, Preslav Asenov, Jesse Smeets +3
Quantum entanglement between gamma-ray photons emitted following electron-positron annihilation is expected to be maximal and may be characterized via non-classical polarization co…

Quantum Estimation in QED Scattering
Preslav Asenov, WenHan Zhang, Alessio Serafini
We tackle the issue of estimating dynamical parameters in quantum electrodynamics. We numerically compute the quantum Fisher information matrix (QFIM) of physical parameters in ele…
