Semidefinite tests for quantum network topologies
Johan Åberg, Ranieri Nery, Cristhiano Duarte +1
Quantum networks play a major role in long-distance communication, quantum cryptography, clock synchronization, and distributed quantum computing. Generally, these protocols involv…
Fully quantum fluctuation theorems
Johan Aberg
Systems that are driven out of thermal equilibrium typically dissipate random quantities of energy on microscopic scales. Crooks fluctuation theorem relates the distribution of the…
Catalytic Coherence
Johan Aberg
Due to conservation of energy we cannot directly turn a quantum system with a definite energy into a superposition of different energies. However, if we have access to an additiona…
Truly work-like work extraction
Johan Aberg
The work content of non-equilibrium systems in relation to a heat bath is often analyzed in terms of expectation values of an underlying random work variable. However, we show that…
The thermodynamic meaning of negative entropy
Lídia del Rio, Johan Aberg, Renato Renner +2
Landauer's erasure principle exposes an intrinsic relation between thermodynamics and information theory: the erasure of information stored in a system, S, requires an amount of wo…
Min- and Max-Entropy in Infinite Dimensions
Fabian Furrer, Johan Aberg, Renato Renner
We consider an extension of the conditional min- and max-entropies to infinite-dimensional separable Hilbert spaces. We show that these satisfy characterizing properties known from…
