Abstract

Abstract We investigate the majorization procedure for mixed unitary quantum channels. The conditions under which we get the exact estimation are found. The example based upon projective unitary representations of Abelian groups is considered.

On Majorization of Quantum Channels by Probability Distributions

Grigori Gennadievich Amosov

Abstract Based on the concept of majorization for the probability distribution, a definition of the majorization of a quantum channel by a probability distribution is introduced. It is shown that the proposed approach makes it possible to solve the problem of taking the extremes of convex functions from the output eigenvalues of mixed unitary channels in the case when summation in the definition of the channel is carried out according to the Heisenberg–Weyl group.

The Role of Covariancy in Calculating Capacity of Quantum Channels Generated by Projective Unitary Representations of Non-Abelian Groups

Grigori Gennadievich Amosov, L. A. Ryskin

Abstract We study quantum channels generated by irreducible projective unitary representations of finite groups. It is shown that to calculate a classical capacity of channel it is not necessary to claim that it is covariant with respect to a representation. It helps to consider non-Abelian groups because in this case such channels are not covariant respect to the generating representation.

On characteristics of mixed unitary channels being additive or multiplicative with respect to taking tensor products

Grigori Gennadievich Amosov

We study mixed unitary channels generated by finite subgroups of the group of all unitary operators in a Hilbert space. Based on the majorization theory we introduce techniques allowing to calculate different characteristics of output states of channels. A class of channels has been allocated for which the use of entangled states doesn't give any advantage under taking supremum and infimum for output characteristics of channels. In particular, $l_p$-norms are multiplicative and the minimal entropy is additive with respect to taking tensor products of channels. As an important application of the obtained results the classical capacity of channel is calculated in the evident form. We compare our techniques with the informational characteristics of Boson quantum channels.

Symbols of mixed unitary quantum channels generated by finite unitary groups

Grigori Gennadievich Amosov, Danil D. Cheremukhin

We study the symbols of linear operators generated by a finite unitary group. Under some assumptions, it is shown that the operator can be restored from its symbol. We also introduce symbols of mixed unitary quantum channels generated by finite unitary groups. An example illustrating the technique is given.

Detecting mixed-unitary quantum channels is NP-hard

Colin Do-Yan Lee, John Watrous

A quantum channel is said to be a mixed-unitary channel if it can be expressed as a convex combination of unitary channels. We prove that, given the Choi representation of a quantum channel Φ , it is NP-hard with respect to polynomial-time Turing reductions to determine whether or not Φ is a mixed-unitary channel. This hardness result holds even under the assumption that Φ is not within an inverse-polynomial distance (in the dimension of the space upon which Φ acts) of the boundary of the mixed-unitary channels.
