Experimental probe of quantum coherence in top-quark pair production
Saeed Haddadi, Majid Azizi, Artur Czerwinski +1
We investigate quantum coherence in top--antitop spin states produced at the LHC using the -norm of coherence applied to the reconstructed spin density matrix. Combining Stand…
Phase-Driven Precision Boost in Quantum Compression for Postselected Metrology
Aiham M. Rostom, Saeed Haddadi, Vladimir A. Tomilin
We reveal the noncyclic Pancharatnam phase--arising from the coherent system-meter interaction--as a fundamental criterion that governs the optimal performance of quantum compressi…
Optical downlink modeling for low-earth-orbit and medium-earth-orbit satellites under atmospheric turbulence with a quantum-state-tomography use case
Artur Czerwinski, Jakub J. Borkowski, Saeed Haddadi +1
This paper presents a comprehensive analysis of the link budget for free-space optical systems involving Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) satellites. We develop a…
Single-photon emission modeling with statistical estimators for the exponential distribution
Artur Czerwinski, Katarzyna Czerwinska, Xiangji Cai +5
Single-photon sources are used in numerous quantum technologies, from sensing and imaging to communication, making the accurate modeling of their emissions essential. In this work,…
Performance of a Superconducting Quantum Battery
Samira Elghaayda, Asad Ali, Saif Al-Kuwari +3
Finding a quantum battery model that demonstrates a quantum advantage while remaining feasible for experimental production is a considerable challenge. Here, a superconducting quan…
A comparative study of LQU and LQFI in general qubit-qutrit axially symmetric states
M. A. Yurischev, Saeed Haddadi, Mehrdad Ghominejad
We derive the compact closed forms of local quantum uncertainty (LQU) and local quantum Fisher information (LQFI) for hybrid qubit-qutrit axially symmetric (AS) states. This allows…
