  Parrondo's paradox, a counterintuitive phenomenon where two losing strategies
combine to produce a winning outcome, has been a subject of interest across
various scientific fields, including quantum mechanics. In this study, we
investigate the manifestation of Parrondo's paradox in discrete-time quantum
walks. We demonstrate the existence of Parrondo's paradox using space and
time-dependent coins without the need for a higher-dimensional coin or adding
decoherence to the system. Our results enhance the feasibility of practical
implementations and provide deeper insights into the underlying quantum
dynamics, specifically the propagation constrained by the interference pattern
of quantum walks. The implications of our results suggest the potential for
more accessible and efficient designs in quantum transport, broadening the
scope and application of Parrondo's paradox beyond conventional frameworks.
