Optimal Multi-port-based Teleportation Schemes
Marek Mozrzymas, Michał Studziński, Piotr Kopszak
In this paper, we introduce optimal versions of a multi-port based teleportation scheme allowing to send a large amount of quantum information. We fully characterise probabilistic…
Efficient multi port-based teleportation schemes
Michał Studziński, Marek Mozrzymas, Piotr Kopszak +1
In this manuscript we analyse generalised port-based teleportation (PBT) schemes, allowing for transmitting more than one unknown quantum state (or a composite quantum state) in on…
Multiport based teleportation -- transmission of a large amount of quantum information
Piotr Kopszak, Marek Mozrzymas, Michał Studziński +1
We analyse the problem of transmitting a number of unknown quantum states or one composite system in one go. We derive a lower bound on the performance of such process, measured in…
Limitations for private randomness repeaters
Karol Horodecki, Ryszard P. Kostecki, Roberto Salazar +1
Cryptographic protocols are often based on the two main resources: private randomness and private key. In this paper, we develop a relationship between these two resources. First,…
