Mixing Times in Quantum Walks on the Hypercube
F. L. Marquezino, R. Portugal, G. Abal +1
The mixing time of a discrete-time quantum walk on the hypercube is considered. The mean probability distribution of a Markov chain on a hypercube is known to mix to a uniform dist…

Asymptotic entanglement in the discrete-time quantum walk
G. Abal, R. Donangelo, H. Fort
The coin-position entanglement generated by the evolution operator of a discrete--time quantum walk converges, in the long time limit, to a well defined value which depends on the…

Decoherent quantum walks driven by a generic coin operation
G. Abal, R. Donangelo, F. Severo +1
We consider the effect of different unitary noise mechanisms on the evolution of a quantum walk (QW) on a linear chain with a generic coin operation: (i) bit-flip channel noise, re…
