Operational Collapse Region in Repeaterless Loss-Dephasing Quantum Channels
Ufuk Korkmaz, S. Elham Mousavigharalari, Deniz Türkpençe
The distribution of entangled photon pairs over standard optical fiber is a fundamental requirement for the realization of the quantum internet. However, real-world deployment is s…

Characterizing Phase Fragility via Algorithmically Prepared Ancillas in Repeated-Interaction Models
S. Elham Mousavigharalari, Deniz Türkpençe
We study how a phase parameter , encoded through a single-qubit gate sequence, is reflected in the quantum Fisher information (QFI) under realistic noisy dynamics. Wit…

Nonclassical features of the pointer states in the -deformed post-selected weak measurement
Seyyede Elham Mousavigharalari, Azmi Ali Altintas, Fatih Ozaydin
We study -deformed coherent states of the Arik-Coon harmonic oscillator as the quantum resource in the post-selected weak measurement. First, we show how the precision of weak m…
