Quantum state tomography with quantum shot noise

Samuelsson, Peter LU and Buttiker, M (2006) In Physical Review B (Condensed Matter and Materials Physics) 73(4).
Abstract
We propose a scheme for a complete reconstruction of one- and two-particle orbital quantum states in mesoscopic conductors. The conductor in the transport state continuously emits orbital quantum states. The orbital states are manipulated by electronic beam splitters and detected by measurements of average currents and zero frequency current shot-noise correlators. We show how, by a suitable complete set of measurements, the elements of the density matrices of the one- and two-particle states can be directly expressed in terms of the currents and current correlators.
