    "abstract": "We show that quantum walks interpolate between a coherent `wave walk\u0027 and a\nrandom walk depending on how strongly the walker\u0027s coin state is measured;\ni.e., the quantum walk exhibits the quintessentially quantum property of\ncomplementarity, which is manifested as a trade-off between knowledge of which\npath the walker takes vs the sharpness of the interference pattern. A physical\nimplementation of a quantum walk (the quantum quincunx) should thus have an\nidentifiable walker and the capacity to demonstrate the interpolation between\nwave walk and random walk depending on the strength of measurement.",
