Quantum tomography allows to expand operators over functions of a continuous set of spectral den- sities — the so-called quorum of observables. We present new nontrivial operator expansions for the quorum of quadratures of the harmonic oscillator, and introduce a general framework to generate new expansions based on the Kolmogorov construction.

Abstract
Quantum tomography allows to expand operators over functions of a continuous set of spectral den- sities — the so-called quorum of observables. We present new nontrivial operator expansions for the quorum of quadratures of the harmonic oscillator, and introduce a general framework to generate new expansions based on the Kolmogorov construction.File in questo prodotto:
