Regularized Compton double scattering via unitarity
Shanmuka Shivashankara, Isra Gashi
When two initially entangled photons each undergo Compton scattering, the scattered electrons become correlated. However, the final reduced density matrix of one scattered pair is…

Unitarity constrains the quantum information metrics for particle interactions
Shanmuka Shivashankara, Hobbes Sprague
Unitarity provides mathematical and physical constraints on quantum information systems. e.g., in entanglement swapping, unitarity requires the same von Neumann entanglement entrop…
