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…
Exponentially decreasing critical detection efficiency for any Bell inequality
Nikolai Miklin, Anubhav Chaturvedi, Mohamed Bourennane +2
We address the problem of closing the detection efficiency loophole in Bell experiments, which is crucial for real-world applications. Every Bell inequality has a critical detectio…
Universal method for optimized robustness in self-testing of quantum resources
Shin-Liang Chen, Nikolai Miklin
Self-testing is a phenomenon where the use of specific quantum states or measurements can be inferred solely from the correlations they generate. We introduce a universal method fo…
Sound certification of memory-bounded quantum computers
Jan Nöller, Nikolai Miklin, Martin Kliesch +1
The rapid advancement of quantum hardware calls for the development of reliable methods to certify its correct functioning. However, existing certification tests often fall short:…
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…
