Witnessing the architecture of quantum circuits
Raphaël Mothe, Otfried Gühne
Determining whether a target unitary can be implemented within a prescribed quantum circuit architecture is a fundamental problem in quantum information, with direct implications f…
Correlations and quantum circuits with dynamical causal order
Raphaël Mothe, Alastair A. Abbott, Cyril Branciard
Requiring that the causal structure between different parties is well-defined imposes constraints on the correlations they can establish, which define so-called causal correlations…
Reassessing the advantage of indefinite causal orders for quantum metrology
Raphaël Mothe, Cyril Branciard, Alastair A. Abbott
The quantum switch, the canonical example of a process with indefinite causal order, has been claimed to provide various advantages over processes with definite causal orders for s…
Comparing the quantum switch and its simulations with energetically-constrained operations
Marco Fellous-Asiani, Raphaël Mothe, Léa Bresque +5
Quantum mechanics allows processes to be superposed, leading to a genuinely quantum lack of causal structure. For example, the process known as the quantum switch applies two opera…
