Secure communication over generalised quantum multiple access channels
Tamoghna Das, Karol Horodecki, Robert Pisarczyk
We investigate the security of generalized quantum multiple-access channels. We provide the formula for the achievable rate region of secure communication in the scenario of two se…
Genuine multipartite indistinguishability and its detection via generalized Hong-Ou-Mandel effect
Marcin Karczewski, Robert Pisarczyk, Paweł Kurzyński
The question whether two indistinguishable particles are bosons or fermions can be answered by observing the Hong-Ou-Mandel effect on a beam splitter. However, already for three pa…
Causal limit on quantum communication
Robert Pisarczyk, Zhikuan Zhao, Yingkai Ouyang +2
The capacity of a channel is known to be equivalent to the highest rate at which it can generate entanglement. Analogous to entanglement, the notion of a causality measure characte…
