Harnessing Nth Root Gates for Energy Storage
Elliot Fox, Marcela Herrera, Ferdinand Schmidt-Kaler +1
We explore the use of fractional control-not gates in quantum thermodynamics. The Nth-root gate allows for a paced application of two-qubit operations. We apply it in quantum therm…
Correlation-boosted quantum engine: A proof-of-principle demonstration
Marcela Herrera, John H. Reina, Irene D'Amico +1
Employing currently available quantum technology, we design and implement a non-classically correlated SWAP heat engine that allows to achieve an efficiency above the standard Carn…
Easy access to energy fluctuations in non-equilibrium quantum many-body systems
Marcela Herrera, John P. S. Peterson, Roberto M. Serra +1
We combine theoretical and experimental efforts to propose a method for studying energy fluctuations, in particular, to obtain the related bi-stochastic matrix of transition probab…
Efficiency of free auxiliary models in describing interacting fermions: from the Kohn-Sham model to the optimal entanglement model
Kristian Patrick, Marcela Herrera, Jake Southall +2
Density functional theory maps an interacting Hamiltonian onto the Kohn-Sham Hamiltonian, an explicitly free model with identical local fermion densities. Using the interaction dis…
Melting a Hubbard dimer: benchmarks of `ALDA' for quantum thermodynamics
Marcela Herrera, Krissia Zawadzki, Irene D'Amico
The competition between evolution time, interaction strength, and temperature challenges our understanding of many-body quantum systems out-of-equilibrium. Here we consider a bench…
Experimental characterization of a spin quantum heat engine
John P. S. Peterson, Tiago B. Batalhão, Marcela Herrera +4
Developments in the thermodynamics of small quantum systems envisage non-classical thermal machines. In this scenario, energy fluctuations play a relevant role in the description o…
DFT-inspired methods for quantum thermodynamics
Marcela Herrera, Roberto M. Serra, Irene D'Amico
In the framework of quantum thermodynamics, we propose a method to quantitatively describe thermodynamic quantities for out-of-equilibrium interacting many-body systems. The method…
Nonadiabatic quantum state engineering driven by fast quench dynamics
Marcela Herrera, Marcelo S. Sarandy, Eduardo I. Duzzioni +1
There are a number of tasks in quantum information science that exploit non-transitional adiabatic dynamics. Such a dynamics is bounded by the adiabatic theorem, which naturally im…
