    "abstract": "We propose a scheme utilising a quantum interference phenomenon to switch the\ntransport of atoms in a 1D optical lattice through a site containing an\nimpurity atom. The impurity represents a qubit which in one spin state is\ntransparent to the probe atoms, but in the other acts as a single atom mirror.\nThis allows a single-shot quantum non-demolition measurement of the qubit spin.",
