Avoiding irreversibility: engineering resonant conversions of quantum resources
Kamil Korzekwa, Christopher T. Chubb, Marco Tomamichel
We identify and explore the intriguing property of resource resonance arising within resource theories of entanglement, coherence and thermodynamics. While the theories considered…
Moderate deviation analysis of majorisation-based resource interconversion
Christopher T. Chubb, Marco Tomamichel, Kamil Korzekwa
We consider the problem of interconverting a finite amount of resources within all theories whose single-shot transformation rules are based on a majorisation relation, e.g. the re…
Jointly constrained semidefinite bilinear programming with an application to Dobrushin curves
Stefan Huber, Robert Koenig, Marco Tomamichel
We propose a branch-and-bound algorithm for minimizing a bilinear functional of the form \[ f(X,Y) = \mathrm{tr}((X\otimes Y)Q)+\mathrm{tr}(AX)+\mathrm{tr}(BY) , \] of pairs of Her…
Minimax quantum state estimation under Bregman divergence
Maria Quadeer, Marco Tomamichel, Christopher Ferrie
We investigate minimax estimators for quantum state tomography under general Bregman divergences. First, generalizing the work of Komaki et al. $\href{http://dx.doi.org/10.3390/e19…
Partially smoothed information measures
Anurag Anshu, Mario Berta, Rahul Jain +1
Smooth entropies are a tool for quantifying resource trade-offs in (quantum) information theory and cryptography. In typical bi- and multi-partite problems, however, some of the su…
Quantum Channel Simulation and the Channel's Smooth Max-Information
Kun Fang, Xin Wang, Marco Tomamichel +1
We study the general framework of quantum channel simulation, that is, the ability of a quantum channel to simulate another one using different classes of codes. First, we show tha…
