Beyond Hoeffding and Chernoff: Trading conclusiveness for advantages in quantum hypothesis testing
Kaiyuan Ji, Bartosz Regula
The ultimate limits of quantum state discrimination are often thought to be captured by asymptotic bounds that restrict the achievable error probabilities, notably the quantum Cher…
Quantum umlaut information
Filippo Girardi, Aadil Oufkir, Bartosz Regula +3
We study the quantum umlaut information, a correlation measure defined for bipartite quantum states as a reversed variant of the quantum mutual information: $U(A;B)_ρ= \mi…
Umlaut information
Filippo Girardi, Aadil Oufkir, Bartosz Regula +3
The sphere-packing bound quantifies the error exponent for noisy channel coding for rates above a critical value. Here, we study the zero-rate limit of the sphere-packing bound and…
Tight relations and equivalences between smooth relative entropies
Bartosz Regula, Ludovico Lami, Nilanjana Datta
The precise one-shot characterisation of operational tasks in classical and quantum information theory relies on different forms of smooth entropic quantities. A particularly impor…
