Higher-order quantum thermodynamics: equilibrium and causal structure
Simon Milz, Kyrylo Simonov, Zoltán Zimborás +3
Quantum thermodynamics is traditionally formulated as a theory of equilibrium states and state transformations. Recent advances in higher-order quantum transformations, which descr…
Entanglement-enhanced fluctuation-free daemonic ergotropy with random measurements
Saptarshi Roy, Pritam Halder, Tamal Guha +1
Optimized daemonic ergotropy can make entanglement thermodynamically dispensable in measurement-assisted work extraction: for a fixed system marginal, quantum-classical states can…
Hierarchies of Gaussian multimode entanglement from thermodynamic quantifiers
Mrinmoy Samanta, Sudipta Mondal, Ayan Patra +2
We develop a thermodynamic characterization of multimode entanglement in pure continuous-variable systems by quantifying the gap between globally and locally extractable work (ergo…
The communication power of a noisy qubit
Giulio Chiribella, Saptarshi Roy, Tamal Guha +1
A fundamental limitation of quantum communication is that a single qubit can carry at most 1 bit of classical information. For an important class of quantum communication channels,…
Operational Ergotropy: suboptimality of the geodesic drive
Pritam Halder, Srijon Ghosh, Saptarshi Roy +1
We put forth a notion of optimality for extracting ergotropic work, derived from an energy constraint governing the necessary dynamics for work extraction in a quantum system. With…
Activation of thermal states by coherently controlled thermalization processes
Kyrylo Simonov, Saptarshi Roy, Tamal Guha +2
Thermalization processes degrade the states of any working medium, turning any initial state into a passive state from which no work can be extracted. Recently, it has been shown t…
