Testing real quantum theory in an optical quantum network
Zheng-Da Li, Ya-Li Mao, Mirjam Weilenmann +12
Quantum theory is commonly formulated in complex Hilbert spaces. However, the question of whether complex numbers need to be given a fundamental role in the theory has been debated…
Entanglement in prepare-and-measure scenarios: many questions, a few answers
Jef Pauwels, Armin Tavakoli, Erik Woodhead +1
Entanglement and quantum communication are paradigmatic resources in quantum information science leading to correlations between systems that have no classical analogue. Correlatio…
Operational nonclassicality in minimal autonomous thermal machines
Jonatan Bohr Brask, Fabien Clivaz, Géraldine Haack +1
Thermal machines exploit interactions with multiple heat baths to perform useful tasks, such as work production and refrigeration. In the quantum regime, tasks with no classical co…
Full network nonlocality
Alejandro Pozas-Kerstjens, Nicolas Gisin, Armin Tavakoli
Networks have advanced the study of nonlocality beyond Bell's theorem. Here, we introduce the concept of full network nonlocality, which describes correlations that necessitate all…
Bell nonlocality in networks
Armin Tavakoli, Alejandro Pozas-Kerstjens, Ming-Xing Luo +1
Bell's theorem proves that quantum theory is inconsistent with local physical models. It has propelled research in the foundations of quantum theory and quantum information science…
Correlations in entanglement-assisted prepare-and-measure scenarios
Armin Tavakoli, Jef Pauwels, Erik Woodhead +1
We investigate the correlations that can arise between Alice and Bob in prepare-and-measure communication scenarios where the source (Alice) and the measurement device (Bob) can sh…
Quantum theory based on real numbers can be experimentally falsified
Marc-Olivier Renou, David Trillo, Mirjam Weilenmann +5
While complex numbers are essential in mathematics, they are not needed to describe physical experiments, expressed in terms of probabilities, hence real numbers. Physics however a…
Semi-device-independent framework based on restricted distrust in prepare-and-measure experiments
Armin Tavakoli
A semi-device-independent framework for prepare-and-measure experiments is introduced in which an experimenter can tune the degree of distrust in the performance of the quantum dev…
