Trotter errors from dynamical structural instabilities of Floquet maps in quantum simulation
Karthik Chinni, Manuel H. Muñoz-Arias, Ivan H. Deutsch +1
We study the behavior of errors in the quantum simulation of spin systems with long-range multi-body interactions resulting from the Trotter-Suzuki decomposition of the time-evolut…
Diverging quantum speed limits: a herald of classicality
Pablo M. Poggi, Steve Campbell, Sebastian Deffner
When is the quantum speed limit (QSL) really quantum? While vanishing QSL times often indicate emergent classical behavior, it is still not entirely understood what precise aspects…
The effect of chaos on the simulation of quantum critical phenomena in analog quantum simulators
Karthik Chinni, Pablo M. Poggi, Ivan H. Deutsch
We study how chaos, introduced by a weak perturbation, affects the reliability of the output of analog quantum simulation. As a toy model, we consider the Lipkin-Meshkov-Glick (LMG…
Nonlinear dynamics and quantum chaos of a family of kicked -spin models
Manuel H. Muñoz-Arias, Pablo M. Poggi, Ivan H. Deutsch
We introduce kicked -spin models describing a family of transverse Ising-like models for an ensemble of spin- particles with all-to-all -body interaction terms occurring…
Generating nonlinearities from conditional linear operations, squeezing and measurement for quantum computation and super-Heisenberg sensing
Mattias T. Johnsson, Pablo M. Poggi, Marco A. Rodríguez +2
Large optical nonlinearities can have numerous applications, ranging from the generation of cat-states for optical quantum computation, through to quantum sensing where the sensiti…
