  A fundamental obstacle for achieving quantum computation is local
decoherence. One way to circumvent this problem rests on the concepts of
topological quantum computation using non-local information storage, for
example on pairs of Majorana fermions (MFs). The arguably most promising way to
generate MFs relies at present on spin-triplet p-wave states of superconductors
(SC), which are not abundant in nature, unfortunately. Thus, proposals for
their engineering in devices, usually via proximity effect from a conventional
SC into materials with strong spinorbit coupling (SOC), are intensively
investigated nowadays. Here we take an alternative path, exploiting the
different connections between fields based on a quartet coupling rule for
fields introduced by one of us, we demonstrate that, for instance, coexisting
Zeeman field with a charge current would provide the conditions to induce
p-wave pairing in the presence of singlet superconductivity. This opens new
avenues for the engineering of robust MFs in various, not necessarily
(quasi-)one-dimensional, superconductor-ferromagnet heterostructures, including
such motivated by recent pioneering experiments that report MFs, in particular,
without the need of any exotic materials with special structures of intrinsic
SOC.
