Logarithmic coherence: Operational interpretation of -norm coherence
Swapan Rana, Preeti Parashar, Andreas Winter +1
We show that the distillable coherence---which is equal to the relative entropy of coherence---is, up to a constant factor, always bounded by the -norm measure of coherence…
Generalized Laws of Thermodynamics in the Presence of Correlations
Manabendra Nath Bera, Arnau Riera, Maciej Lewenstein +1
The laws of thermodynamics, despite their wide range of applicability, are known to break down when systems are correlated with their environments. Here, we generalize thermodynami…
Hybrid annealing using a quantum simulator coupled to a classical computer
Tobias Graß, Maciej Lewenstein
Finding the global minimum in a rugged potential landscape is a computationally hard task, often equivalent to relevant optimization problems. Simulated annealing is a computationa…
Randomness in Quantum Mechanics: Philosophy, Physics and Technology
Manabendra Nath Bera, Antonio Acín, Marek Kuś +2
This progress report covers recent developments in the area of quantum randomness, which is an extraordinarily interdisciplinary area that belongs not only to physics, but also to…
Energy as a detector of nonlocality of many-body spin systems
Jordi Tura, Gemma De las Cuevas, Remigiusz Augusiak +3
We present a method to show that low-energy states of quantum many-body interacting systems in one spatial dimension are nonlocal. We assign a Bell inequality to the Hamiltonian of…
Entanglement and coherence in quantum state merging
A. Streltsov, E. Chitambar, S. Rana +3
Understanding the resource consumption in distributed scenarios is one of the main goals of quantum information theory. A prominent example for such a scenario is the task of quant…
A Lindblad Model of Quantum Brownian Motion
Aniello Lampo, Soon Hoe Lim, Jan Wehr +2
The theory of quantum Brownian motion describes the properties of a large class of open quantum systems. Nonetheless, its description in terms of a Born-Markov master equation, wid…
Random bosonic states for robust quantum metrology
Michał Oszmaniec, Remigiusz Augusiak, Christian Gogolin +3
We study how useful random states are for quantum metrology, i.e., surpass the classical limits imposed on precision in the canonical phase estimation scenario. First, we prove tha…
