Quantum information processing under maximal distance measures
Bartosz Regula, Ludovico Lami, Mario Berta +1
The measures of distance frequently used in quantum information, such as trace distance or fidelity-based purified distance, are the smallest extensions of the corresponding distan…
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…
Error exponent of activated non-signaling assisted classical-quantum channel coding
Aadil Oufkir, Marco Tomamichel, Mario Berta
We provide a tight asymptotic characterization of the error exponent for classical-quantum channel coding assisted by activated non-signaling correlations. Namely, we find that the…
Continuity of entropies via integral representations
Mario Berta, Ludovico Lami, Marco Tomamichel
We show that Frenkel's integral representation of the quantum relative entropy provides a natural framework to derive continuity bounds for quantum information measures. Our main g…
Asymptotic quantification of entanglement with a single copy
Ludovico Lami, Mario Berta, Bartosz Regula
Despite the central importance of quantum entanglement in quantum technologies, the understanding of the optimal ways to exploit it is still beyond our reach, and even measuring en…
Quantum algorithms: A survey of applications and end-to-end complexities
Alexander M. Dalzell, Sam McArdle, Mario Berta +10
The anticipated applications of quantum computers span across science and industry, ranging from quantum chemistry and many-body physics to optimization, finance, and machine learn…
