Large scale statistically validated comorbidity networks
Paride Crisafulli, Tobias Galla, Antti Karlsson +3
We obtain comorbidity networks starting from medical information stored in electronic health records collected by the Wellbeing Services County of Southwest Finland (Varha). Based…
Quantum Zeno effect and non-Markovianity in a three-level system
Antti Karlsson, Francesco Francica, Jyrki Piilo +1
We study the coexistence of the quantum Zeno effect and non-Markovianity for a system decaying in a structured bosonic environment and subject to a control field. The interaction w…
Verifying the quantumness of bipartite correlations
Claudio Carmeli, Teiko Heinosaari, Antti Karlsson +2
Entanglement is at the heart of most quantum information tasks, and therefore considerable effort has been made to find methods of deciding the entanglement content of a given bipa…
Non-Markovian dynamics in two-qubit dephasing channels with an application to superdense coding
Antti Karlsson, Henri Lyyra, Elsi-Mari Laine +2
We study the performance of two measures of non-Markovianity in detecting memory effects in two-qubit dephasing channels. By combining independent Markovian and non-Markovian noise…
Efficient superdense coding in the presence of non-Markovian noise
Bi-Heng Liu, Xiao-Min Hu, Yun-Feng Huang +7
Many quantum information tasks rely on entanglement, which is used as a resource, for example, to enable efficient and secure communication. Typically, noise, accompanied by loss o…
Locality and universality of quantum memory effects
B. -H. Liu, S. Wißmann, X. -M. Hu +7
Recently, a series of different measures quantifying memory effects in the quantum dynamics of open systems has been proposed. Here, we derive a mathematical representation for the…
Optimal state pairs for non-Markovian quantum dynamics
Steffen Wissmann, Antti Karlsson, Elsi-Mari Laine +2
We study a recently proposed measure for the quantification of quantum non-Markovianity in the dynamics of open systems which is based on the exchange of information between the op…
