Classical versus non-classical photon states for detecting vacuum non-linearity
N. Ahmadiniaz, C. Kohlfürst, R. Shaisultanov +1
Quantum electrodynamics (QED) predicts that the vacuum should behave as a non-linear medium. For many schemes aimed at verifying this fundamental prediction, the signal consists of…
Quantum Zeno effect versus adiabatic quantum computing and quantum annealing
Naser Ahmadiniaz, Dennis Kraft, Gernot Schaller +1
For the adiabatic version of Grover's quantum search algorithm as proposed by Roland and Cerf, we study the impact of decoherence caused by a rather general coupling to some enviro…
Relativistic Quantum Kinetic Theory: Higher order contributions in assisted Schwinger pair production
James P. Edwards, Naser Ahmadiniaz, Sebastian M. Schmidt +1
Quantum kinetic theory is an important tool for studying non-equilibrium, non-perturbative and non-linear interactions within an open quantum system, and as such is able to provide…
Worldline integration of photon amplitudes
Naser Ahmadiniaz, Victor M. Banda Guzmán, James P. Edwards +5
It has been known for many years that methods inspired by string theory, such as the worldline formalism, allow one to write down integral representations that combine large number…
