Quantum advantage from negativity of a work quasiprobability distribution
Gianluca Francica
Quantum batteries can be charged by performing a work ``instantaneously'' in the limit of a large number of cells, achieving a so-called quantum advantage. In general, the work exh…
Quantum advantage unlocked: Charging quantum batteries with K-regular graph stabilizers
Debkanta Ghosh, Tanoy Kanti Konar, Amit Kumar Pal +2
Regular graphs find broad applications ranging from quantum communication to quantum computation. Motivated by this, we investigate the design of a quantum battery based on a K-reg…
Quantum advantage in batteries for Sachdev-Ye-Kitaev interactions
Gianluca Francica
A quantum advantage can be achieved in the unitary charging of quantum batteries if their cells are interacting. Here, we try to clarify with some analytical calculations whether a…
Resource theories with completely passive states and passive states as free states
Gianluca Francica
Work extractable from quantum system can be viewed as a resource to perform some tasks. Here, we try to related the work extractable to some resource theory. To do this, we conside…
Work fluctuation theorems with initial quantum coherence
Gianluca Francica, Luca Dell'Anna
Fluctuation theorems are fundamental results in nonequilibrium thermodynamics beyond the linear response regime. Among these, the paradigmatic Tasaki-Crooks fluctuation theorem rel…
Role of quantum correlations in daemonic expected utility
Gianluca Francica, Luca Dell'Anna
Fluctuations can challenge the possibility of improving work extraction from quantum correlations. This uncertainty in the work extraction process can be addressed resorting to the…
