- Abstract: Black holes are conjectured to be the fastest information scramblers, and
within holographic duality, the speed of quantum information scrambling of
thermal states of quantum systems is at the heart of studies of chaos and black
hole dynamics. Here, considering the Ising interaction on the thermal state of
spin chains with Dzyaloshinskii-Moriya (DM) interaction and measuring the
out-of-time-order correlation functions, we study the effect of DM interaction
on the speed of scrambling the quantum information. On the contrary to its
advantages in quantum information and metrology such as exciting entanglement
and quantum Fisher information, we show that DM interaction speeds up the
information scrambling. We also show that the increasing temperature slows down
the scrambling process due to vanishing quantum correlations.
