One qubit almost completely reveals the dynamics of two
Thomas F. Jordan, Anil Shaji, E. C. G. Sudarshan
From the time dependence of states of one of them, the dynamics of two interacting qubits is determined to be one of two possibilities that differ only by a change of signs of para…
Does The Uncertainty Relation Determine The Quantum State?
Olga V. Man'ko, V. I. Man'ko, G. Marmo +2
The example of nonpositive trace-class Hermitian operator for which Robertson-Schroedinger uncertainty relation is fulfilled is presented. The partial scaling criterion of separabi…
A tomographic setting for quasi-distribution functions
V. I. Man'ko, G. Marmo, A. Simoni +2
The method of constructing the tomographic probability distributions describing quantum states in parallel with density operators is presented. Known examples of Husimi-Kano quasi-…
Relations Between Quantum Maps and Quantum States
M. Asorey, A. Kossakowski, G. Marmo +1
The relation between completely positive maps and compound states is investigated in terms of the notion of quantum conditional probability.
