Thermodynamic bound on the Fano factor of a coherent thermoelectric heat engine
Nahual Sobrino, Rosario Fazio, Matteo Acciai
The paper derives universal lower bounds on the Fano factor for charge currents in coherent thermoelectric heat engines, showing that quantum coherent transport imposes stricter li…
Spectral and transmission properties of multiple correlated quantum dots made simple
Nahual Sobrino, Stefan Kurth
Steady-state density functional theory, called i-DFT, is employed to compute spectral and transmission properties of general interacting nanoscale regions coupled to electronic res…
Quantum thermodynamic uncertainty relation and macroscopic superconducting coherence
Franco Mayo, Nahual Sobrino, Rosario Fazio +2
Stability and efficiency are mutually exclusive in a thermodynamic process, e.g. in a thermal machine. Any effort to reduce the fluctuations of a certain output quantity is necessa…
Current precision in interacting hybrid Normal-Superconducting systems
Nahual Sobrino, Fabio Taddei, Rosario Fazio +1
We study Andreev-mediated transport and current fluctuations in interacting normal-superconducting quantum-dot systems. Using a generalized master equation based on real-time diagr…
Thermoelectric properties of interacting double quantum dots
Nahual Sobrino
We investigate the thermoelectric transport properties of an interacting parallel double quantum dot in the Coulomb-blockade regime. Building on an analytical solution based on an…
A Useful Metric for the NISQ Era: Qubit Error Probability and Its Role in Zero Noise Extrapolation
Nahual Sobrino, Unai Aseginolaza, Joaquim Jornet-Somoza +1
Accurate assessment and management of errors is indispensable for extracting useful results from noisy intermediate-scale quantum (NISQ) devices. In this work, we propose the qubit…
