Quantum noise generated by local random Hamiltonians
Marcin Markiewicz, Zbigniew Puchala, Anna de Rosier +2
We investigate the impact of a local random unitary noise on multipartite quantum states of an arbitrary dimension. We follow the dynamical approach, in which the single-particle u…
Investigating nonclassicality of many qutrits by symmetric two-qubit operators
Marcin Markiewicz, Kamil Kostrzewa, Adrian Kolodziejski +2
We introduce a new method of investigating qutrit nonclassicality by translating qutrit operators to symmetric two-qubit operators. We show that this procedure partially resolves t…
Three-dimensional visualization of a qutrit
Pawel Kurzynski, Adrian Kolodziejski, Wieslaw Laskowski +1
We present a surprisingly simple three-dimensional Bloch sphere representation of a qutrit, i.e., a single three-level quantum system. We start with a symmetric state of a two-qubi…
