  Localized states in graphene have garnered significant attention in quantum
information science due to their potential applications. Despite graphene's
superior transport and electronic properties compared to other semiconductors,
achieving nanoscale confinement remains challenging due to its gapless nature.
In this study, we explore the unique transport properties along nanowrinkles in
monolayer graphene. We demonstrate the creation of a one-dimensional conduction
channel by alternating pseudo-magnetic fields along the nanowrinkle, enabling
ballistic Dirac fermion transport without leakage. This suggests a feasible
method for secure quantum information transfer over long distances.
Furthermore, we extend our analysis to bent nanowrinkles, showcasing
well-guided Dirac fermion propagation unless the bent angle is sufficiently
large. Our demonstration of the nanowrinkle waveguide in graphene introduces a
novel approach to controlling Dirac fermion transport through strain
engineering, for quantum information technology applications.
