An operator algebraic approach for generalized Cardano polynomials
Leonard Mada, Maria Anastasia Jivulescu
We develop an operator algebraic framework for generalized Cardano polynomials and show how their structure naturally leads to an operator formulation of Cardano method that is com…
Calculating the Projective Norm of higher-order tensors using a gradient descent algorithm
Aaditya Rudra, Maria Anastasia Jivulescu
Projective Norms are a class of tensor norms that map on the input and output spaces. These norms are useful for providing a measure of entanglement. Calculating the projective nor…
Order preserving maps on quantum measurements
Teiko Heinosaari, Maria Anastasia Jivulescu, Ion Nechita
We study the partially ordered set of equivalence classes of quantum measurements endowed with the post-processing partial order. The post-processing order is fundamental as it ena…
Multipartite entanglement detection via projective tensor norms
Maria Anastasia Jivulescu, Cécilia Lancien, Ion Nechita
We introduce and study a class of entanglement criteria based on the idea of applying local contractions to an input multipartite state, and then computing the projective tensor no…
Random positive operator valued measures
Teiko Heinosaari, Maria Anastasia Jivulescu, Ion Nechita
We introduce several notions of random positive operator valued measures (POVMs), and we prove that some of them are equivalent. We then study statistical properties of the effect…
Absolutely separating quantum maps and channels
Sergey N. Filippov, Kamil Yu. Magadov, Maria Anastasia Jivulescu
Absolutely separable states remain separable under arbitrary unitary transformations . By example of a three qubit system we show that in multipartite scen…
