Topologically Protected Learning from Exceptional Point Braiding: Toward Braid Programming
M. N. Jipdi, C. Avomo Mba, A. B. Moubissi +2
We present a framework for topological learning based on exceptional point (EP) braiding in a non-Hermitian Bogoliubov-de Gennes Hamiltonian. A closed algebraic equation for the EP…

Longitudinal-Field-Driven Transition in a non-integrable Non-Hermitian Transverse-Field Ising Chain via RBMs
M. E. Ateuafack, M. R. Kamsap, J. T. Diffo +2
We investigate the ground-state properties and quantum critical behavior of a non-Hermitian transverse-field Ising chain subjected to longitudinal and complex transverse magnetic f…

Dynamics of entanglement and state-space trajectories followed by a system of four-qubit in the presence of random telegraph noise: common environment (CE) versus independent environments (IEs)
L. T. Kenfack, M. Tchoffo, M. N. Jipdi +2
The paper investigates the dynamics of entanglement and explores some geometrical characteristics of the trajectories in state space, in four-qubit Greenberger-Horne-Zeilinger (GHZ…
