Quantum Fisher information of the Klein--Gordon and Dirac vacua
Preslav Asenov, Alessio Serafini
The quantum Fisher information (QFI) of the vacuum of three quantum field theories is evaluated with respect to the mass parameter of each theory. All field theories are considered…
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…
QEDtool: A Python package for numerical quantum information in quantum electrodynamics
Jesse Smeets, Preslav Asenov, Alessio Serafini
This is the manual of the first version of QEDtool, an object-oriented Python package that performs numerical quantum electrodynamics calculations, with focus on full state reconst…
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…
