Experimental Quantum Key Distribution in an Indefinite Causal Order
Yann Valibouse, Martí Cladera-Rosselló, Michael Antesberger +6
In quantum physics the order in which different operations occur can be placed in superposition. The resulting processes have an indefinite causal order and are both of fundamental…

Indefinite causal key distribution
Hector Spencer-Wood
We propose a quantum key distribution (QKD) protocol that is carried out in an indefinite causal order (ICO). In QKD, one considers a setup in which two parties, Alice and Bob, sha…
