Causal inference with imperfect instrumental variables
Nikolai Miklin, Mariami Gachechiladze, George Moreno +1
Instrumental variables allow for quantification of cause and effect relationships even in the absence of interventions. To achieve this, a number of causal assumptions must be met,…
A convergent inflation hierarchy for quantum causal structures
Laurens T. Ligthart, Mariami Gachechiladze, David Gross
A causal structure is a description of the functional dependencies between random variables. A distribution is compatible with a given causal structure if it can be realized by a p…
Experimental test of quantum causal influences
Iris Agresti, Davide Poderini, Beatrice Polacchi +8
Since Bell's theorem, it is known that the concept of local realism fails to explain quantum phenomena. Indeed, the violation of a Bell inequality has become a synonym of the incom…
Quantum Bell inequalities from Information Causality -- tight for Macroscopic Locality
Mariami Gachechiladze, Bartłomiej Bąk, Marcin Pawłowski +1
In a Bell test, the set of observed probability distributions complying with the principle of local realism is fully characterized by Bell inequalities. Quantum theory allows for a…
Quantifying causal influences in the presence of a quantum common cause
Mariami Gachechiladze, Nikolai Miklin, Rafael Chaves
Quantum mechanics challenges our intuition on the cause-effect relations in nature. Some fundamental concepts, including Reichenbach's common cause principle or the notion of local…
Changing the circuit-depth complexity of measurement-based quantum computation with hypergraph states
Mariami Gachechiladze, Otfried Gühne, Akimasa Miyake
While the circuit model of quantum computation defines its logical depth or "computational time" in terms of temporal gate sequences, the measurement-based model could allow totall…
The structure of ultrafine entanglement witnesses
Mariami Gachechiladze, Nikolai Wyderka, Otfried Gühne
An entanglement witness is an observable with the property that a negative expectation value signals the presence of entanglement. The question arises how a witness can be improved…
Graphical description of unitary transformations on hypergraph states
Mariami Gachechiladze, Nikoloz Tsimakuridze, Otfried Gühne
Hypergraph states form a family of multiparticle quantum states that generalizes cluster states and graph states. We study the action and graphical representation of nonlocal unita…
Completing the proof of "Generic quantum nonlocality"
Mariami Gachechiladze, Otfried Gühne
In a paper by Popescu and Rohrlich [Phys. Lett. A 166, 293 (1992)] a proof has been presented showing that any pure entangled multiparticle quantum state violates some Bell inequal…
Extreme violation of local realism in quantum hypergraph states
Mariami Gachechiladze, Costantino Budroni, Otfried Gühne
Hypergraph states form a family of multiparticle quantum states that generalizes the well-known concept of Greenberger-Horne-Zeilinger states, cluster states, and more broadly grap…
