Universal measurement of quantum correlations of radiation
E. Shchukin, W. Vogel
A measurement technique is proposed which, in principle, allows one to observe the general space-time correlation properties of a quantized radiation field. Our method, called bala…

Inseparability criteria for bipartite quantum states
E. Shchukin, W. Vogel
We provide necessary and sufficient conditions for the partial transposition of bipartite harmonic quantum states to be nonnegative. The conditions are formulated as an infinite se…
