Characterizing quantum channels from local-unitary invariants
Salwa Shaglel, Satoya Imai
We develop systematic frameworks for characterizing the entanglement properties of two-qubit channels beyond unitary settings. We introduce averaged local-unitary invariants, refer…

A comprehensive benchmark of an Ising machine on the Max-Cut problem
Salwa Shaglel, Markus Kirsch, Marten Winkler +4
QUBO formulations of combinatorial optimization problems allow for solving them using various quantum heuristics. While large-scale quantum computations are currently still out of…

Asymptotic entanglement sudden death in two atoms with dipole-dipole and Ising interactions coupled to a radiation field at non-zero detuning
Gehad Sadiek, Wiam Al-Drees, Salwa Shaglel +1
We investigate the time evolution and asymptotic behavior of a system of two two-level atoms (qubits) interacting off-resonance with a single mode radiation field. The two atoms ar…
