Entanglement in quantum channel discrimination: sometimes less is more
Kristin Sundal Lien, Marco Túlio Quintino
Entanglement is known to be a powerful resource that improves performance in various quantum information and computational tasks. A standard example of such a phenomenon is the pos…
Can every set of incompatible measurements lead to genuine multipartite steering?
Lucas E. A. Porto, Lucas Tendick, Daniel Cavalcanti +2
Measurement incompatibility and bipartite quantum steering are known to display a strong connection: a set of measurements is incompatible if and only if it can lead to bipartite s…
Double Recurrence and Almost Sure Convergence: Primes and Weighted Theory
Jan Fornal, Ben Krause
Let be a probability space equipped with an invertible, measure-preserving transformation . We exhibit a wide class of weights so that whenever $f,g \i…
Post-measurement states are (very) useful for measurement discrimination
Charbel Eid, Marco Túlio Quintino
The standard approach to quantum measurement discrimination is to perform the given unknown measurement on a probe state, possibly entangled with an auxiliary system, and make a de…
Composable simultaneous purification: when all communication scenarios reduce to spatial correlations
Matilde Baroni, Dominik Leichtle, Ivan Šupić +2
Bell non-locality is a powerful framework to distinguish classical, quantum and post-quantum resources, which relies on non-communicating players. Under which restriction can we ha…
Higher-order quantum computing with known input states
Vanessa Brzić, Satoshi Yoshida, Mio Murao +1
In higher-order quantum computing (HOQC), one typically considers the universal transformation of unknown quantum operations, treated as blackboxes. It is also implicitly assumed t…
