Correlations and quantum circuits with dynamical causal order Open
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. Some of these are known to have a "dynamical" causal orde…

Reassessing the advantage of indefinite causal orders for quantum metrology Open
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 some particular tasks in the field of quantum metrology. In …

Comparing the quantum switch and its simulations with energetically constrained operations Open
Quantum mechanics allows processes to be superposed, leading to a genuinely\nquantum lack of causal structure. For example, the process known as the quantum\nswitch applies two operations ${\\cal A}$ and ${\\cal B}$ in a superposition of\n…

Report on 2005.04939v1 Open
We present a detailed theoretical and experimental analysis of Engineered Swift Equilibration (ESE) protocols applied to two hydrodynamically coupled colloids in optical traps.The second particle slightly perturbs (10% at most) the respons…
