Reply to the comment on "Quantum priniple of relativity"

Andrzej Dragan, Artur Ekert

We refute criticisms by Del Santo and Horvat towards our paper "Quantum principle of relativity": most of their counterarguments can be dismissed, and the rest provides further evi…

Reply to Galilean invariance without superluminal particles

Andrzej Dragan, Artur Ekert

In a recent comment [arXiv:2112.05658], Grudka and Wójcik object to some of our earlier claims concerning a link between fundamental postulates of quantum theory and special relati…

Security analysis of quantum key distribution with small block length and its application to quantum space communications

Charles Ci-Wen Lim, Feihu Xu, Jian-Wei Pan +1

The security of real-world quantum key distribution (QKD) critically depends on the number of data points the system can collect in a fixed time interval. To date, state-of-the-art…

Quantum principle of relativity

Andrzej Dragan, Artur Ekert

We show that the local and deterministic mode of description is not only in conflict with the quantum theory, but also with relativity. We argue that elementary relativistic proper…

Decoherence-assisted transport in quantum networks

A. Marais, I. Sinayskiy, A. Kay +2

It is shown that energy transfer in a homogeneous fully connected quantum network is assisted by a decohering interaction with environmental spins. Analytic expressions for the tra…
