Comment on "Environmental memory effects and quantum resource hierarchies in polarized hyperon--antihyperon systems"
Saeed Haddadi
We comment on the recent work [Eur. Phys. J. C 86, 988 (2026)], which investigates quantum resources in polarized hyperon--antihyperon systems using correlated dephasing channels w…
Orthogonality Edges in Strong-Coupling Quantum Work Statistics
Atta ur Rahman, Muhammad Noman, S. M. Zangi +1
Strong coupling to a reservoir can do more than shift, broaden, or dress the work peaks of a driven quantum system. When the reservoir is infrared singular, a sudden change of a lo…
Quantum Information Resources in Spin-1 Heisenberg Dimer Systems
Fadwa Benabdallah, M. Y. Abd-Rabbou, Mohammed Daoud +1
We explore the quantum information resources within bipartite pure and mixed states of the quantum spin-1 Heisenberg dimer system, considering some interesting factors such as the…
Quantum Characteristics Near Event Horizons
Asad Ali, Saif Al-Kuwari, Mehedad Ghominejad +3
We investigate quantum characteristics around Schwarzschild black hole, exploring various quantum resources and their interplay in curved space-time. Our analysis reveals intriguin…
Gravitational cat states as a resource for quantum information processing
Atta ur Rahman, Ao-Xiang Liu, Saeed Haddadi +1
We investigate how resourceful gravitational cat states are to preserve quantum correlations. In this regard, we explore the dynamics of gravitational cat states under different si…
Thermal local quantum uncertainty in a two-qubit-superconducting system under decoherence
M. R. Pourkarimi, S. Haddadi, M. Nashaat +2
By considering the local quantum uncertainty (LQU) as a measure of quantum correlations, the thermal evolution of a two-qubit-superconducting system is investigated. We show that t…
Does conditional entropy squeezing indicate normalized entropic uncertainty relation steering?
A-S. F. Obada, M. Y. Abd-Rabbou, Saeed Haddadi
A novel approach is introduced to assess one-way Normalized Entropic Uncertainty Relations (NEUR)-steering in a two-qubit system by utilizing an average of conditional entropy sque…
Local quantum Fisher information and local quantum uncertainty for general X-states
M. A. Yurischev, Saeed Haddadi
A two-spin-1/2 Heisenberg XYZ model with Dzyaloshinsky--Moriya (DM) and Kaplan--Shekhtman--Entin-Wohlman--Aharony (KSEA) interactions in the presence of an inhomogeneous external m…
Quantum dynamical speedup for correlated initial states
Alireza Gholizadeh, Maryam Hadipour, Soroush Haseli +2
The maximal evolution speed of any quantum system can be expressed by the quantum speed limit time. In this paper, we consider a model in which the system has a correlation with th…
Quantum speed limit of Jaynes-Cummings model with detuning for arbitrary initial states
Yasin Shahri, Maryam Hadipour, Saeed Haddadi +2
The quantum speed limit (QSL) of the Jaynes-Cummings model with detuning for arbitrary initial states is investigated. We mainly focus on the influences of the detuning, width of L…
Quantum Otto heat engines on XYZ spin working medium with DM and KSEA interactions: Operating modes and efficiency at maximal work output
Elena I. Kuznetsova, M. A. Yurischev, Saeed Haddadi
The magnetic Otto thermal machine based on a two-spin-1/2 XYZ working fluid in the presence of an inhomogeneous magnetic field and antisymmetric Dzyaloshinsky--Moriya (DM) and symm…
Tripartite quantum-memory-assisted entropic uncertainty relations for multiple measurements
Hazhir Dolatkhah, Saeed Haddadi, Soroush Haseli +2
Quantum uncertainty relations are typically analyzed for a pair of incompatible observables, however, the concept per se naturally extends to situations of more than two observable…
Quantum speed limit time for moving qubit inside leaky cavity
Maryam Hadipour, Soroush Haseli, Hazhir Dolatkhah +1
The minimum time required for a quantum system to evolve from an arbitrary initial state to its orthogonal state is known as the quantum speed limit (QSL) time. In this work, we co…
Entropic uncertainty lower bound for a two-qubit system coupled to a spin chain with Dzyaloshinskii-Moriya interaction
Soroush Haseli, Saeed Haddadi, Mohammad Reza Pourkarimi
The uncertainty principle is one of the key concepts in quantum theory. This principle states that it is not possible to measure two incompatible observables simultaneously and acc…
