  Majorana-zero-modes (MZMs) were predicted to exist as edge states of a
physical system called the Kitaev chain. MZMs should host particles that are
their own antiparticles and could be used as a basis for a qubit which is
robust-to-noise. However, all attempts to prove their existence gave
inconclusive results. Here, the Kitaev chain is exactly solved with a quantum
computing methodology and properties of MZMs are probed by generating
eigenstates of the Kitev Hamiltonian on 3 noisy qubits of a publicly available
quantum computer. After an ontological elaboration I show that two eigenstates
of the Kitaev Hamiltonian exhibit eight signatures attributed to MZMs. The
results presented here are a most comprehensive set of validations of MZMs ever
conducted in an actual physical system. Furthermore, the findings of this
manuscript are easily reproducible for any user of publicly available quantum
computers, solving another important problem of research with MZMs-the result
reproducibility crisis.
