Magnetic skyrmions promise unique opportunities for the processing, storage and transfer of information by means of ultrathin metallic nanostructures at the intersection of both spintronics and nanoelectronics [
Fert 2013,
Nagaosa 2013,
Sampaio 2013,
Iwasaki 2013,
Zhang 2015,
Koshibae 2015]. They appear ubiquitously in diverse systems whenever the competition between Dzyaloshinski-Moriya interaction (DMI) and other magnetic energy contributions result in an equilibrium spin texture that is strongly adverse to deformations. As a result, skyrmions are exceptionally stable structures capable of withstanding room-temperature environments [
Jiang 2015,
Woo 2016] and being manipulated at extremely small current densities (
\(\sim 10^{6}\mathrm{A}/\mathrm{m}^2\)) with negligible ohmic heating as compared to domain walls [

The appeal of skyrmions is so wide that it has defined a field of its own,
skyrmionics, which refers to the emerging technologies based on magnetic skyrmions as information carriers. In an effort to push for the commercialization of skyrmion electronics, challenges ranging from their creation and annihilation [
Nagaosa 2013,
Zhang 2015,
Tchoe 2012], the conversion of their topological properties [
Zhou 2014,
Zhang 2015], as well as their efficient transmission and read-out [
Nagaosa 2013,
Iwasaki 2013,
Sampaio 2013,
Tomasello 2014,
Koshibae 2015] are being tackled and solved. Their nano-metric size and high mobility [
Muhlbauer 2009,
Lin 2013,
Yu 2010,
Fert 2013] has successfully been exploited in the context of skyrmion-based racetrack memories [
Zhang 2015,
Kang 2016], logic gates [
Zhang 2015] and as voltage-gated transistors [
Zhang 2015].
In this paper, we explicitly address the problem of leveraging the repulsions exhibited by interacting skyrmions with their thermal diffusion to demonstrate how skyrmions may be employed to perform probabilistic computing. Particularly we will show how a very compact device can be modelled for the reshuffling of stochastic telegraph noise signals and random number generation. In conclusion, we will argue how the device in question, subject to trivial modifications, can serve a much more general purpose by effectively working as an anlog integrate-and-fire neuron. We believe this lays the groundwork for the application of skyrmionic devices as bio-inspired building blocks for non-conventional computing paradigms.
