Scalable Test of Genuine Multipartite Entanglement via Partially Randomized Measurements
Jan Wojcik, Pawel Chrabkowski, Wieslaw Laskowski
Certifying genuine multipartite entanglement in quantum systems can require a number of measurements that grows exponentially with the system size. Here we introduce a criterion ba…
A Cross-Cultural Analysis of Animated Representations of Emotions for Wearable Interfaces
Michal R. Wrobel, Duygun Erol Barkana, Agnieszka Landowska
Although pervasive sensing technologies are increasingly capable of continuously detecting human emotional states, there is still a critical challenge: how to unobtrusively communi…
On the biggest purely non-free conformal actions on compact Riemann surfaces and their asymptotic properties
C. Bagiński, G. Gromadzki, R. A. Hidalgo
A continuous action of a finite group on a closed orientable surface is said to be gpnf (Gilman purely non-free) if every element of has a fixed point on . We prove…
Battery-Explicit Thermodynamic Witnesses of Bell Post-Quantumness
Piotr Ćwikliński
We introduce a battery-explicit thermodynamic witness of post-quantum Bell correlations. In each round, a single supplied excitation is routed into an explicit two-level battery if…
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…
Time-Dependent Logarithmic Perturbation Theory for Quantum Dynamics: Formulation and Applications
Juan Carlos del Valle, Paul Bergold, Karolina Kropielnicka
We present a time-dependent extension of logarithmic perturbation theory for nonrelativistic quantum dynamics governed by the Schrödinger equation, in which the logarithm of the wa…
