Stronger Welch Bounds and Optimal Approximate -Designs
Riccardo Castellano, Dmitry Grinko, Sadra Boreiri +2
The question of how well a finite ensemble of quantum states can approximate Haar randomness is relevant in many areas of quantum physics. Here we consider this problem from a geom…
Parallel ergotropy: Maximum work extraction via parallel local unitary operations
Riccardo Castellano, Ranieri Nery, Kyrylo Simonov +1
Maximum quantum work extraction is generally defined in terms of the ergotropy functional, no matter how experimentally complicated is the implementation of the optimal unitary all…
Extended local ergotropy
Riccardo Castellano, Donato Farina, Vittorio Giovannetti +1
A fundamental problem in quantum thermodynamics is to properly quantify the work extractable from out-of-equilibrium systems. While for closed systems, maximum quantum work extract…
