Out-of-time-ordered correlators and the Loschmidt echo in the quantum kicked top: How low can we go?
Sreeram PG, Vaibhav Madhok, Arul Lakshminarayan
The out-of-time-ordered correlators (OTOC) and the Loschmidt echo are two measures that are now widely being explored to characterize sensitivity to perturbations and information s…

Exponential speedup in measuring out-of-time-ordered correlators with a single bit of quantum information
Sreeram PG, Naga Dileep Varikuti, Vaibhav Madhok
Out-of-time-ordered correlators (OTOC) are a quantifier of quantum information scrambling and quantum chaos. We propose an efficient quantum algorithm to measure OTOCs that provide…
