Accuracy in Quantum Homodyne Tomography
Giacomo Mauro D’Ariano, Chiara Macchiavello, Nicoletta Sterpi · Kluwer Academic Publishers eBooks · 2005
We study the statistical errors in homodyne tomography of radiation density matrix in the photon number representation. We give an asymptotic estimate for large matrix indexes at different values of the quantum efficiency η of homodyne detectors. We show that for fixed η the errors increase exponentially as functions of the matrix index.
