Randomizing Quantum Walk
Rashid Ahmad, Safia Bibi, Uzma Sajjad
The evolution of a walker in standard "Discrete-time Quantum Walk (DTQW)" is determined by coin and shift unitary operators. The conditional shift operator shifts the position of t…

One-Dimensional Quantum Walks with a Position-Dependent Coin
Rashid Ahmad, Uzma Sajjad, Muhammad Sajid
We investigate the evolution of a discrete-time one-dimensional quantum walk driven by a position-dependent coin. The rotation angle which depends upon the position of a quantum pa…
