Ultimate speed limits to the growth of operator complexity
In an isolated system, the time evolution of a given observable in the Heisenberg picture can
be efficiently represented in Krylov space. In this representation, an initial operator becomes …

Unifying quantum and classical speed limits on observables
The presence of noise or the interaction with an environment can radically change the
dynamics of observables of an otherwise isolated quantum system. We derive a bound on …

Speed limit for classical stochastic processes
We consider the speed limit for classical stochastic Markov processes with and without the
local detailed balance condition. We find that, for both cases, a trade-off inequality exists …

Stochastic time evolution, information geometry, and the Cramér-Rao bound
We investigate the connection between the time evolution of averages of stochastic
quantities and the Fisher information and its induced statistical length. As a consequence of …

Time–information uncertainty relations in thermodynamics
Physical systems powering motion and creating structure in a fixed amount of time dissipate
energy and produce entropy. Whether living, synthetic or engineered, systems performing …

Driving rapidly while remaining in control: classical shortcuts from Hamiltonian to stochastic dynamics
Stochastic thermodynamics lays down a broad framework to revisit the venerable concepts
of heat, work and entropy production for individual stochastic trajectories of mesoscopic …

Topological speed limit
Any physical system evolves at a finite speed that is constrained not only by the energetic
cost but also by the topological structure of the underlying dynamics. In this Letter, by …
