Machine Learning of Quantum Entanglement from Noisy Measurements
Artur Czerwinski, Maciej Wiśniewski, Paweł Moszczyński
In this work, we investigate the application of Machine Learning (ML) algorithms to the identification and quantitative characterization of quantum entanglement in polarization-ent…
Optimization of two-photon excitation by indistinguishable photons in a three-level atom
Masood Valipour, Gniewomir Sarbicki, Karolina Słowik +1
We investigate the excitation of a three-level ladder-type atom by a unidirectional field with a pair of indistinguishable photons. Starting from an analytical expression for the t…
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…
Practical and Efficient Verification of Entanglement with Incomplete Measurement Settings
Jiheon Seong, Jin-Woo Kim, Seungchan Seo +6
In this work, we present a practical and efficient framework for verifying entangled states when only a tomographically incomplete measurement setting is available-specifically, wh…
Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
Stochastic unravelings allow to efficiently simulate open system dynamics, yet their application has traditionally been restricted to master equations that preserve both Hermiticit…
Spectroscopy and Coherence of an Excited-State Transition in Tm:YAlO at Telecommunication Wavelength
Luozhen Li, Akshay Babu Karyath, Julien Bertrand +12
We characterize spectroscopic and coherence properties of the 1451.37 nm excited-state zero-phonon line (ZPL) between the and the manifolds of a thulium-dop…
