Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states

open access: yesNature Communications, 2016
Cloning an unknown quantum state is challenging and the limit on the quality of clones is set by the no-cloning theorem. Here, the authors demonstrated the surpassing of such a limit using an effective quantum cloner based on a hybrid probabilistic ...

Hyperentanglement concentration of nonlocal two-photon six-qubit systems via the cross-Kerr nonlinearity

open access: yesScientific Reports, 2020
We present an efficient hyperentanglement concentration protocol (hyper-ECP) for two-photon six-qubit systems in nonlocal partially hyperentangled Bell states with unknown parameters.

Directed quantum communication

open access: yes, 2013
We raise the question whether there is a way to characterize the quantum information transport properties of a medium or material. For this analysis the special features of quantum information have to be taken into account.

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

open access: yesAdvanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.
