Remote polarization entanglement generation by local dephasing and frequency upconversion
S. Hamedani Raja, G. Karpat, E. -M. Laine +4
We introduce a scheme for remote entanglement generation for the photon polarization. The technique is based on transferring the initial frequency correlations to specific polariza…
The problem of coherent control in non-Markovian open quantum systems
Carole Addis, Elsi-Mari Laine, Clemens Gneiting +1
We critically evaluate the most widespread assumption in the theoretical description of coherent control strategies for open quantum systems. We show that, for non-Markovian open s…
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…
Dynamics of incompatibility of quantum measurements in open systems
Carole Addis, Teiko Heinosaari, Jukka Kiukas +2
The non-classical nature of quantum states, often illustrated using entanglement measures or quantum discord, constitutes a resource for quantum information protocols. However, the…
Non-Markovian dynamics in open quantum systems
Heinz-Peter Breuer, Elsi-Mari Laine, Jyrki Piilo +1
The dynamical behavior of open quantum systems plays a key role in many applications of quantum mechanics, examples ranging from fundamental problems, such as the environment-induc…
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…
