Semi-Device-Independent Certification of Causal Nonseparability with Trusted Quantum Inputs
Hippolyte Dourdent, Alastair A. Abbott, Nicolas Brunner +2
While the standard formulation of quantum theory assumes a fixed background causal structure, one can relax this assumption within the so-called process matrix framework. Remarkabl…

Quantum circuits with classical versus quantum control of causal order
Julian Wechs, Hippolyte Dourdent, Alastair A. Abbott +1
Quantum supermaps are transformations that map quantum operations to quantum operations. It is known that quantum supermaps which respect a definite, predefined causal order betwee…
