  Exotic states of topological materials are challenging or impossible to
create under ambient conditions.1-4 Moreover, it is unclear whether topological
superconductivity, as a critical element for topological quantum computing,
exists in any naturally occurring materials.5-7 Although these problems can be
overcome through the combination of materials in heterostructures, there are
still many requisites, such as low temperatures and specific magnetic
fields.8,9 Herein, an intrinsic topological superconductor that does not depend
on particular external conditions is demonstrated. It is accomplished utilizing
the unique properties of polyaromatic hydrocarbons (PAHs), which have been
proposed to have persistent ring current.10-12 According to the
Su-Schrieffer-Heeger(SSH)13 and Kitaev14 models, PAHs can have a non-trivial
edge mode, so that perpendicularly stacked PAHs are expected to have Majorana
hinge and corner modes.15 Intrinsic persistent ring current of HYLION-12 is
demonstrated by MPMS.16 Coherent Quantum Phase Slip(CQPS), the Constant
Conductance Plateau (CCP) and the zero bias conductance peak(ZBP) which is
signatures of hinge modes are confirmed through the Josephson junction device
of pelletized orthorhombic phase organic crystals of HYLION-12 by transport
spectroscopy.17,18 They are signatures of Majorana hinge and corner modes. In
addition, the braidinglike operation by transport spectroscopy shows the
emergence of the most important and critical elements of quantum computers that
can be realized without an external magnetic field at room temperature.
