Simplification of Additivity Conjecture in Quantum Information Theory
نویسنده
چکیده
We simplify some conjectures in quantum information theory; the additivity of minimal output entropy, the multiplicativity of maximal output p-norm and the superadditivity of convex closure of output entropy. We construct a unital channel for a given channel so that they share the above additivity properties; we can reduce the conjectures for all channels to those for unital channels.

Yet another additivity conjecture
In quantum information theory, there are several important open problems which center around whether certain quantities are additive or not. Especially, additivity conjecture about Holevo capacity and additivity/strong superadditivity conjecture about entanglement of formation have been attracting many researchers. It recently turned out that these are equivalent to the additivity of the minimu...
متن کاملOn the multiplicativity conjecture for quantum channels
A multiplicativity conjecture for quantum communication channels is formulated, validity of which for the values of parameter p close to 1 is related to the solution of the fundamental problem of additivity of the channel capacity in quantum information theory. The proof of the conjecture is given for the case of natural numbers p.
متن کاملOn Some Additivity Problems in Quantum Information Theory
Quantum information theory [2] is not merely a theoretical basis for physics of information and computation. It is also a source of challenging mathematical problems, often having elementary formulation but still resisting solution. It appears that surprisingly little is known about what may be called the combinatorial geometry of tensor products of Hilbert spaces, even in finite dimensions. On...
متن کاملEquivalence of Additivity Questions in Quantum Information Theory
We reduce the number of open additivity problems in quantum information theory by showing that four of them are equivalent. Namely, we show that the conjectures of additivity of the minimum output entropy of a quantum channel, additivity of the Holevo expression for the classical capacity of a quantum channel, additivity of the entanglement of formation, and strong superadditivity of the entang...
متن کاملThe capacity of the quantum depolarizing channel
The information carrying capacity of the d-dimensional depolarizing channel is computed. It is shown that this capacity can be achieved by encoding messages as products of pure states belonging to an orthonormal basis of the state space, and using measurements which are products of projections onto this same orthonormal basis. In other words, neither entangled signal states nor entangled measur...
