Towards minimal self-testing of qubit states and measurements in prepare-and-measure scenarios
Gábor Drótos, Károly F. Pál, Abdelmalek Taoutioui +1
Self-testing is a promising approach to certifying quantum states or measurements. Originally, it relied solely on the outcome statistics of the measurements involved in a device-i…
Demonstration of EPR steering using single-photon path entanglement and displacement-based detection
T. Guerreiro, F. Monteiro, A. Martin +15
We demonstrate the violation of an EPR steering inequality developed for single photon path entanglement with displacement-based detection. We use a high-rate source of heralded si…
Quantum advantage for distributed computing without communication
L. Czekaj, M. Pawlowski, T. Vertesi +3
Understanding the role that quantum entanglement plays as a resource in various information processing tasks is one of the crucial goals of quantum information theory. Here we prop…
A two-qubit Bell inequality for which POVM measurements are relevant
T. Vértesi, E. Bene
A bipartite Bell inequality is derived which is maximally violated on the two-qubit state space if measurements describable by positive operator valued measure (POVM) elements are…
Maximal violation of the I3322 inequality using infinite dimensional quantum systems
K. F. Pál, T. Vértesi
The I3322 inequality is the simplest bipartite two-outcome Bell inequality beyond the Clauser-Horne-Shimony-Holt (CHSH) inequality, consisting of three two-outcome measurements per…
Concavity of the quantum body for any given dimension
K. F. Pál, T. Vértesi
Let us consider the set of all joint probabilities generated by local binary measurements on two separated quantum systems of a given local dimension d. We address the question of…
