Harnessing Floquet dynamics for selective metrology in few-qubit systems
Asghar Ullah, Hasan Mermer, Melih Özkurt +2
Periodically driven quantum systems can function as highly selective parameter filters. We demonstrate this capability in a finite-size, three-qubit system described by the transve…

Pseudo-Hermiticity, Anti-Pseudo-Hermiticity, and Generalized Parity-Time-Reversal Symmetry at Exceptional Points
Nil İnce, Hasan Mermer, Ali Mostafazadeh
For a diagonalizable linear operator acting in a separable Hilbert space , i.e., an operator with a purely point spectrum, eigenvalues wi…
