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…
Making the most of leftovers: Improved privacy amplification for quantum key distribution
Matthew Simon Tan, Bartosz Regula, Marco Tomamichel
The amount of secret key that can be obtained from a quantum key distribution run depends on both the physically observed error rates and the mathematical bounds used to certify se…
Reliability of asymptotic work extraction
Kaito Watanabe, Bartosz Regula, Marco Tomamichel +1
Extracting work from quantum states is a fundamental task in quantum thermodynamics. Previous studies have primarily focused on determining the best achievable rate of work extract…
Universal quantum resource distillation via composite generalised quantum Stein's lemma
Ludovico Lami, Bartosz Regula, Ryuji Takagi
The performance of quantum resource manipulation protocols, including key examples such as distillation of quantum entanglement, is measured in terms of the rate at which desired t…
Rethinking quantum smooth entropies: Tight one-shot analysis of quantum privacy amplification
Bartosz Regula, Marco Tomamichel
We introduce an improved one-shot characterisation of randomness extraction against quantum side information (privacy amplification), strengthening known one-shot bounds and provid…
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…
