Bounds for the divisibility-based and distinguishability-based non-Markovianity measures
H. Mäkelä
We derive an upper bound for the distinguishability-based non-Markovianity measure of a two-level system and prove that for certain master equations the exact value of the measure…

N-qubit states as points on the Bloch sphere
H. Mäkelä, A. Messina
We show how the Majorana representation can be used to express the pure states of an N-qubit system as points on the Bloch sphere. We compare this geometrical representation of N-q…

Polynomial method to study the entanglement of pure N-qubit states
H. Mäkelä, A. Messina
We present a mapping which associates pure N-qubit states with a polynomial. The roots of the polynomial characterize the state completely. Using the properties of the polynomial w…
