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…
