Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons

open access: yesAdvanced Quantum Technologies, EarlyView.
Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware

open access: yesAdvanced Quantum Technologies, EarlyView.
Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

High‐Purity Single‐Photon Emission in the Telecom O‐Band from Droplet‐Epitaxy InAs Quantum Dots Integrated into a GaAs/AlGaAs Planar Microcavity on Vicinal GaAs(111)A Platform

open access: yesAdvanced Quantum Technologies, EarlyView.
High‐purity single‐photon emission at telecom O‐band is demonstrated from droplet‐epitaxy InAs quantum dots embedded in a GaAs/AlGaAs microcavity. Strain engineering via an InAlAs buffer enables broadband telecom emission with high purity, short lifetimes, and enhanced extraction.

Nanotubes from Transition Metal Dichalcogenides: Recent Progress in the Synthesis, Characterization and Electrooptical Properties

open access: yesSmall, EarlyView.
This review describes recent (mostly last five years) progress in the synthesis, structural characterization, and properties of nanotubes from layered transition metal dichalcogenides, including in‐silico investigations. In the picture, ultra long multiwall nanotubes (up to 0.5 mm) nanotubes reported in Ref.

Optimization of Interfacial Electrons and Compressive‐Tensile Strains at Lignin‐Derived Carbon‐Supported Multiphase Ni/Cu/MoO2 Interfaces for Boosting Large Current‐Density HER

open access: yesSmall, EarlyView.
The physicochemical and electrochemical results of Ni/Cu/MoO2@LC show that the multiphase interfaces formed by Ni, Cu, MoO2, and lignin‐derived carbon produce a synergistic effect of interfacial electron transfer and compressive‐tensile strains, which significantly improves HER activity and stability in a full pH range. Abstract Developing efficient pH‐
