State convertibility and fluctuation theorems from a dynamical reference: majorization meets martingales
Davide Cugini, Giacomo Guarnieri
State convertibility represents a fundamental concept used to determine whether a transformation is possible given a specific set of resources. Within the field of Thermodynamics,…
Symmetry-guided quantum state preparation: Branched-Subspaces Adiabatic Preparation (B-SAP)
Davide Cugini, Giacomo Guarnieri, Mario Motta +1
Quantum state preparation lies at the heart of quantum computation and quantum simulations, enabling the investigation of complex manybody systems across physics, chemistry, and da…
Universal emergence of local Zipf-Mandelbrot law
Davide Cugini, André Timpanaro, Giacomo Livan +1
A plethora of natural and socio-economic phenomena share a striking statistical regularity, that is the magnitude of elements decreases with a power law as a function of their posi…
Exponential optimization of adiabatic quantum-state preparation
Davide Cugini, Davide Nigro, Mattia Bruno +1
The preparation of a given quantum state on a quantum computing register is a typically demanding operation, requiring a number of elementary gates that scales exponentially with t…
