On Variational Expressions for Quantum Relative Entropies
Mario Berta, Omar Fawzi, Marco Tomamichel
Distance measures between quantum states like the trace distance and the fidelity can naturally be defined by optimizing a classical distance measure over all measurement statistic…
Exponential Decay of Matrix -Entropies on Markov Semigroups with Applications to Dynamical Evolutions of Quantum Ensembles
Hao-Chung Cheng, Min-Hsiu Hsieh, Marco Tomamichel
In the study of Markovian processes, one of the principal achievements is the equivalence between the -Sobolev inequalities and an exponential decrease of the -entropies. In…
Tomography is necessary for universal entanglement detection with single-copy observables
Dawei Lu, Tao Xin, Nengkun Yu +7
Entanglement, one of the central mysteries of quantum mechanics, plays an essential role in numerous applications of quantum information theory. A natural question of both theoreti…
Maximum privacy without coherence, zero-error
Debbie Leung, Nengkun Yu
We study the possible difference between the quantum and the private capacities of a quantum channel in the zero-error setting. For a family of channels introduced by arXiv:1312.49…
Relating the Resource Theories of Entanglement and Quantum Coherence
Eric Chitambar, Min-Hsiu Hsieh
Quantum coherence and quantum entanglement represent two fundamental features of non-classical systems that can each be characterized within an operational resource theory. In this…
Interpretation of the Klein-Gordon Probability Density
Roderick Sutherland
The fact that the probability density expression provided by the Klein-Gordon equation can take on negative values is usually seen as an obstacle to formulating a particle interpre…
