Quantum error mitigation in quantum annealing : General access Advantage2 kink-density and kink-correlators

General access Advantage2 kink density and kink correlators as a function of anneal duration and coupling strength.

This data is relevant to a second version of the paper "Quantum error mitigation in quantum annealing" currently under journal review, an earlier preprint with comparable data at smaller scale is here https://arxiv.org/abs/2311.01306 .

A single file kink_density.csv demonstrates kink density for various anneal durations (ta) and coupling strengths (J).The kink value per-site per-read is k_i = (1 - s_i s_{i+1})/2, s_i denotes the state of spin i.Kink density is estimated as k = , where <> denotes a per-programming site (i=0, .., 1023) and 1000-sample (read-out) average.Mean and variance are given with respect to repeated programmings (number of programmings is either 5 or 160 as indicated).See paper methods.

For each ta and J relevant to the paper a csv is provided for kink correlations as a function of displacement r = 0, .., 1023.Kink correlations are estimated as C(r) = /k^2 - 1, where k is the kink density and <> denotes a per-programming site (i = 0 , .., 1023) and 1000-sample (read-out) average.Mean and variance are given with respect to 160 repeated programmings.See paper methods.
