A Bipartite Quantum Key Distribution Protocol Based on Indefinite Causal Order
Mateusz Leśniak, 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…

Transformation of the discrete logarithm problem over to the QUBO problem using normal bases
Michał Wroński, Mateusz Leśniak
Quantum computations are very important branch of modern cryptology. According to the number of working physical qubits available in general-purpose quantum computers and in quantu…

Privacy for Quantum Annealing. Attack on Spin Reversal Transformations in the case of cryptanalysis
Mateusz Leśniak, Michał Wroński
This paper demonstrates that applying spin reversal transformations (SRT), commonly known as a sufficient method for privacy enhancement in problems solved using quantum annealing,…
