Noise Resilience of Quantum Key Distribution Protocols Secured Against Independent Attacks With One-Way Communication
Adam BÃlek, Ryszard Kukulski, Paulina Lewandowska +2
The paper evaluates how much noise single‑qubit quantum key distribution protocols can tolerate when secured against independent eavesdropping attacks and using one‑way classical c…
Resource-Efficient Variational Quantum Classifier
Petr PtáÄek, Paulina Lewandowska, Ryszard Kukulski
We introduce the unambiguous quantum classifier based on Hamming distance measurements combined with classical post-processing. The proposed approach improves classification perfor…
Benchmarking quantum devices beyond classical capabilities
RafaÅ BistroÅ, Rafał Bistroń, Marcin RudziÅski +4
Rapid development of quantum computing technology has led to a wide variety of sophisticated quantum devices. Benchmarking these systems becomes crucial for understanding their cap…
A Bipartite Quantum Key Distribution Protocol Based on Indefinite Causal Order
Mateusz LeÅniak, Ryszard Kukulski, Paulina Lewandowska +2
We propose a bipartite quantum key distribution (QKD) protocol based on causal nonseparability: the presence of a resource -- a process matrix -- that does not correspond to any de…
Experimental study of multiple-shot unitary channels discrimination using the IBM Q computers
Adam BÃlek, Jan Hlisnikovský, Tomáš BezdÄk +2
Tasks involving black boxes appear frequently in quantum computer science. An example that has been deeply studied is quantum channel discrimination. In this work, we study the dis…
Shared entanglement for three-party causal order guessing game
Ryszard Kukulski, Paulina Lewandowska, Karol Życzkowski
In a variant of communication tasks, players cooperate in choosing their local strategies to compute a given task later, working separately. Utilizing quantum bits for communicatio…
