Optimal Decompositions of Quantum
نویسندگان
چکیده
Any non-pure quantum state admits an innnity of non-trivial decom-positions. A recent proposal how to measure the information content of a quantum state with reference to a given subalgebra of operators, singles out some of them, called optimal decompositions, which depend both on the state and on the subalgebra. In this paper we start exploring their main features.

Optimal Decompositions with Respect to Entropy and Symmetries
The entropy of a subalgebra, which has been used in quantum ergodic theory to construct a noncommutative dynamical entropy, coincides for N-level systems and Abelian subalgebras with the notion of maximal mutual information of quantum communication theory. The optimal decompositions of mixed quantum states singled out by the entropy of Abelian subalgebras correspond to optimal detection schemes...

متن کاملBroken Symmetries in the Entanglement of Formation
We compare some recent computations of the entanglement of formation in quantum information theory and of the entropy of a subalgebra in quantum ergodic theory. Both notions require optimization over decompositions of quantum states. We show that both functionals are strongly related for some highly symmetric density matrices. Indeed, for certain interesting regions the entanglement of formatio...
متن کاملOptimal Decompositions of Barely Separable States
Two families of bipartite mixed quantum states are studied for which it is proved that the number of members in the optimal-decomposition ensemble — the ensemble realizing the entanglement of formation — is greater than the rank of the mixed state. We find examples for which the number of states in this optimal ensemble can be larger than the rank by an arbitrarily large factor. In one case the...
متن کاملTime-optimal decompositions in SU(2)
A connected Lie group G is generated by its two 1-parametric subgroups exp(tX), exp(tY ) if and only if the Lie algebra of G is generated by {X, Y }. We consider decompositions of elements of G into a product of such exponentials with times t > 0 and study the problem of minimizing the total time of the decompositions for a fixed element of G. We solve this problem for the group SU2 and describ...
