On quantum Lyapunov exponents

Wladyslaw A. Majewski, Marcin Marciniak

It was shown that quantum analysis constitutes the proper analytic basis for quantization of Lyapunov exponents in the Heisenberg picture. Differences among various quantizations o…

Decomposability of extremal positive unital maps on $M_{2}$

Wladyslaw A. Majewski, Marcin Marciniak

A map $ϕ:M_m(\bC)\to M_n(\bC)$ is decomposable if it is of the form $ϕ = ϕ_{1} + ϕ_{2}$ where $ϕ_{1}$ is a CP map while $ϕ_{2}$ is a co-CP map. It is known that if $m = n = 2$ then every positive…

On decomposability of positive maps between $M_{2}$ and $M_{n}$

Wladyslaw A. Majewski, Marcin Marciniak

A map $ϕ:M_m(\bC)\to M_n(\bC)$ is decomposable if it is of the form $ϕ = ϕ_{1} + ϕ_{2}$ where $ϕ_{1}$ is a CP map while $ϕ_{2}$ is a co-CP map. A partial characterization of decomposability fo…
