Variational Quantum Integrated Sensing and Communication
CoRRThe integration of sensing and communication functionalities within a common system is one of the main innovation drivers for next-generation networks. In this paper, we introduce a quantum integrated sensing and communication (QISAC) protocol that leverages entanglement in quantum carriers of information to enable both superdense coding and quantum ...

Advanced Optical Materials, EarlyView.Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes
Advanced Optical Materials, EarlyView.Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.
