Operational Limits of Gravity-Mediated Entanglement
Atta ur Rahman, Muhammad Noman, Ying-Jian Zhu +2
Tests of gravity-mediated entanglement aim to determine whether two massive objects in spatial superposition can become entangled through their mutual gravitational interaction. In…
Quantum-Enhanced Phase Estimation with Photon-Added Even and Odd Coherent States in an SU(1,1) Interferometer
Abdelmajid El Maaroufi, Mouad Ait Maskour, Bouchra Maroufi +2
We investigate phase estimation in an SU(1,1) interferometer employing -photon-added even and odd coherent states as nonclassical input resources. The phase sensitivity is evalu…
Experimental probe of quantum coherence in top-quark pair production at the LHC
Saeed Haddadi, Majid Azizi, Artur Czerwinski +1
We investigate quantum coherence in the spin degrees of freedom of top--antitop pairs produced at the LHC using the -norm of coherence in the helicity basis. Combining Standar…
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, Maciej Wiśniewski +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…
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…
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,…
