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…

Universal bound on the Lyapunov spectrum of quantum master equations

Paolo Muratore-Ginanneschi, Gen Kimura, Frederik vom Ende +1

The spectral properties of positive maps are pivotal for understanding the dynamics of quantum systems interacting with their environment. Furthermore, central problems in quantum…

Detecting Entanglement by State Preparation and Local Measurements

Jaemin Kim, Anindita Bera, Dariusz Chruściński +1

Entanglement witnesses (EWs) are a collection of observables that can characterize separable states and, experimentally, estimating EWs can verify entangled states. In this work, w…

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…

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…

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…
