Strategies for single-shot discrimination of process matrices
Paulina Lewandowska, Łukasz Pawela, Zbigniew Puchała
The topic of causality has recently gained traction quantum information research. This work examines the problem of single-shot discrimination between process matrices which are an…
On the probabilistic quantum error correction
Ryszard Kukulski, Łukasz Pawela, Zbigniew Puchała
Probabilistic quantum error correction is an error-correcting procedure which uses postselection to determine if the encoded information was successfully restored. In this work, we…
Storage and retrieval of von Neumann measurements
Paulina Lewandowska, Ryszard Kukulski, Łukasz Pawela +1
This work examines the problem of learning an unknown von Neumann measurement of dimension from a finite number of copies. To obtain a faithful approximation of the given measu…
Post-Error Correction for Quantum Annealing Processor using Reinforcement Learning
Tomasz Śmierzchalski, Łukasz Pawela, Zbigniew Puchała +2
Finding the ground state of the Ising spin-glass is an important and challenging problem (NP-hard, in fact) in condensed matter physics. However, its applications spread far beyond…
Accessible maps in a group of classical or quantum channels
Koorosh Sadri, Fereshte Shahbeigi, Zbigniew Puchała +1
We study the problem of accessibility in a set of classical and quantum channels admitting a group structure. Group properties of the set of channels, and the structure of the clos…
