  Superconducting qubits already demonstrated potential in emulating coherent
back scattering or weak localization (WL) and tunnelling phenomena however, in
a real multipath system they have not been verified yet.Here we show how a
double-path system can be emulated by a quantum device through construction of
multiple scattering centers in closed paths (detune boxes) and tunnel barriers
with a large return probability (Pr) of electrons. Incorporation of such
arrangements of tunnel barriers can add an extra geometric phase and
demonstrate Aharonov-Bohm type oscillations (phi)0 and (phi/2)0 in a ring and a
tube, respectively. A combination of inter and intra layer tunnelling in a
double-path circuit creates a phase reversal and subsequently weak
anti-localization (WAL) effect with a long coherence time. Finally, angle
dependence of Pr firmly establishes stability of the two-path circuit which is
also associated with a phase reversal due to the inter-path resonance.
