Collectively enhanced high-power and high-capacity charging of quantum batteries via quantum heat engines
Kosuke Ito, Gentaro Watanabe
As a model of so-called quantum battery (QB), quantum degrees of freedom as energy storage, we study a charging protocol of a many-body QB consisting of two-level systems (TLSs…

Generalized energy measurements and quantum work compatible with fluctuation theorems
Kosuke Ito, Peter Talkner, B. Prasanna Venkatesh +1
The probability densities of work that can be exerted on a quantum system initially staying in thermal equilibrium are constrained by the fluctuation relations of Jarzynski and Cro…

Fundamental bound on the power of quantum machines
Kosuke Ito, Takayuki Miyadera
Giving a universal upper bound on the power output of heat engines is a long-standing open problem. We tackle this problem for generic quantum machines in self-contained formulatio…
