Abstract

Following Brun’s formalism for decoherent Discrete Time Quantum Walk (DTQW), a fully analytical formulation of first moment of DTQW has been presented when the quantum walker is subjected to a bit-flip noise and the initial state of the walker is considered to be delocalized up to three lattice sites in 1D. It is shown that when the initial state of the walker is also modulated by an initial phase, particular choice of initial phase angle can nullify the effect of the nonlocality in first moment in short time limit.
