  A quantum magnetic state due to magnetic charges is never observed, even
though they are treated as quantum mechanical variable in theoretical
calculations. Here, we demonstrate the occurrence of a novel quantum disordered
state of magnetic charges in nanoengineered magnetic honeycomb lattice of
ultra-small connecting elements. The experimental research, performed using
spin resolved neutron scattering, reveals a massively degenerate ground state,
comprised of low integer and energetically forbidden high integer magnetic
charges, that manifests cooperative paramagnetism at low temperature. The
system tends to preserve the degenerate configuration even under large magnetic
field application. It exemplifies the robustness of disordered correlation of
magnetic charges in 2D honeycomb lattice. The realization of quantum disordered
ground state elucidates the dominance of exchange energy, which is enabled due
to the nanoscopic magnetic element size in nanoengineered honeycomb.
Consequently, an archetypal platform is envisaged to study quantum mechanical
phenomena due to emergent magnetic charges.
