Quantum Aitchison geometry
Attila Andai, Attila Lovas
Multiplying a likelihood function with a positive number makes no difference in Bayesian statistical inference, therefore after normalization the likelihood function in many cases…
On the notion of quantum copulas
Attila Lovas, Attila Andai
Working with multivariate probability distributions Sklar introduced the notion of copula in 1959, which turned out to be a key concept to understand the structure of distributions…
Volume of the space of qubit-qubit channels and state transformations under random quantum channels
Attila Lovas, Attila Andai
The simplest building blocks for quantum computations are the qubit-qubit quantum channels. In this paper, we analyze the structure of these channels via their Choi representation.…
Invariance of separability probability over reduced states in 4x4 bipartite systems
Attila Lovas, Attila Andai
The geometric separability probability of composite quantum systems is extensively studied in the last decades. One of most simple but strikingly difficult problem is to compute th…
Volume of the space of qubit channels and some new results about the distribution of the quantum Dobrushin coefficient
Attila Lovas, Attila Andai
The simplest building blocks for quantum computations are the qbit-qbit quantum channels. In this paper we analyse the structure of these channels via their Choi representation. Th…
Measure on gauge invariant symmetric norms
Attila Lovas, Attila Andai
The concept of a gauge invariant symmetric random norm is elaborated in this paper. We introduce norm processes and show that this kind of stochastic processes are closely related…
