Indefinite Quantum Causality
Fabio Costa, Giulia Rubino, Cyril Branciard +2
In recent years, operational approaches to quantum foundations have been developed as a means of understanding the core principles and distinctive features of quantum theory. Such…
Nonlocality activation in a photonic quantum network
Luis Villegas-Aguilar, Emanuele Polino, Farzad Ghafari +9
Bell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocal…
Characterising the Hierarchy of Multi-time Quantum Processes with Classical Memory
Philip Taranto, Marco Túlio Quintino, Mio Murao +1
Memory is the fundamental form of temporal complexity: when present but uncontrollable, it manifests as non-Markovian noise; conversely, if controllable, memory can be a powerful r…
Possible consequences for physics of the negative resolution of Tsirelson's problem
Adán Cabello, Marco Túlio Quintino, Matthias Kleinmann
In 2020, Ji et al. [arXiv:2001.04383 and Comm.~ACM 64}, 131 (2021)] provided a proof that the complexity classes and are equivalent. This result impli…
Higher-order Process Matrix Tomography of a passively-stable Quantum SWITCH
Michael Antesberger, Marco Túlio Quintino, Philip Walther +1
The field of indefinite causal order (ICO) has seen a recent surge in interest. Much of this research has focused on the quantum SWITCH, wherein multiple parties act in a superposi…
Characterising transformations between quantum objects, 'completeness' of quantum properties, and transformations without a fixed causal order
Simon Milz, Marco Túlio Quintino
Many fundamental and key objects in quantum mechanics are linear mappings between particular affine/linear spaces. This structure includes basic quantum elements such as states, me…
