Arbitrary coherent distributions in a programmable quantum walk
Rong Zhang, Ran Yang, Jian Guo +7
The coherent superposition of position states in a quantum walk (QW) can be precisely engineered towards the desired distributions to meet the need of quantum information applicati…

Maximal coin-walker entanglement in a ballistic quantum walk
Rong Zhang, Ran Yang, Jian Guo +7
We report the position-inhomogeneous quantum walk (IQW) can be utilized to produce the maximal high dimensional entanglement while maintaining the quadratic speedup spread of the w…
