Information Causality Characterizes the Set of Quantum Correlations in the Simplest Bell Scenario
Mariami Gachechiladze, Nikolai Miklin
Information causality (IC) was introduced as a physical principle constraining correlations in non-signaling theories. Whether it can recover the exact quantum correlation boundary…
Sound and Efficient Certification of High-Quality Qubit Operations: Theory and Experiment
Nikolai Miklin, Jan Nöller, José Martínez +4
Can a high-quality quantum gate be certified when uncharacterized state-preparation and measurement errors are dominant? Can this be achieved with low experimental overhead? Here,…
Bounds on Nonlocality and Random Access Codes from Extended Information Causality Principle
Prabhav Jain, Nikolai Miklin, Mariami Gachechiladze
Information Causality was introduced as a physical principle for constraining the set of nonlocal correlations. In recent work, we proposed an extension of Information Causality th…
Communication complexity bounds from information causality
Nikolai Miklin, Prabhav Jain, Mariami Gachechiladze
Communication complexity, which quantifies the minimum communication required for distributed computation, offers a natural setting for investigating the capabilities and limitatio…
Certifying Quantum Gates via Automata Advantage
Anna Schroeder, Lucas B. Vieira, Jan Nöller +2
There is growing interest in developing rigorous tests of quantumness that are feasible even before practical quantum advantages become a reality. Such tests not only aim to certif…
An infinite hierarchy of multi-copy quantum learning tasks
Jan Nöller, Viet T. Tran, Mariami Gachechiladze +1
Learning properties of quantum states from measurement data is a fundamental challenge in quantum information. The sample complexity of such tasks depends crucially on the measurem…
