Optically Generated 2-Dimensional Photonic Cluster State from Coupled Quantum Dots [PDF]

open access: yes, 2010
We propose a method to generate a two-dimensional cluster state of polarization encoded photonic qubits from two coupled quantum dot emitters. We combine the proposal for generating one-dimensional cluster state strings from a single dot, with a new ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Growth and Characterization of Quantum Dots and Quantum Dots Devices [PDF]

open access: yes, 2003
Quantum dot nanostructures were investigated experimentally and theoretically for potential applications for optoelectronic devices. We have developed the foundation to produce state-of-the-art compound semiconductor nanostructures in a variety of materials: In(AsSb) on GaAs, GaSb on GaAs, and In(AsSb) on GaSb. These materials cover a range of energies

Optical Properties of Quantum-Dot-Doped Liquid Scintillators

open access: yes, 2013
Semiconductor nanoparticles (quantum dots) were studied in the context of liquid scintillator development for upcoming neutrino experiments. The unique optical and chemical properties of quantum dots are particularly promising for the use in neutrinoless

Designing Metastable P3‐type Layered Negative Electrodes with High Na Vacancy Concentration for High‐Power Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A metastable high‐vacancy concentration layered P3‐type Na0.5Cr0.5Ti0.5O2 negative electrode material has been synthesized from its K analogues P3‐type K0.5Cr0.5Ti0.5O2 using a facile room temperature ion‐exchange method. The P3‐type Na0.5Cr0.5Ti0.5O2 demonstrates a gravimetric capacity of 125 mA h g−1 and high‐rate performance (80% charging in 3 min ...

Electrical manipulation of an electronic two-state system in Ge/Si quantum dots [PDF]

open access: yes, 2009
We calculate that the electron states of strained self-assembled Ge/Si quantum dots provide a convenient two-state system for electrical control. An electronic state localized at the apex of the quantum dot is nearly degenerate with a state localized at the base of the quantum dot.

Exciton-phonon coupling and phonon-assisted exciton relaxation dynamics in In1-xGaxP quantum dots

open access: yesNature Communications
Quantum dots leverage quantum confinement to modify the electronic structure of materials, separating electronic transitions from the composition of the corresponding bulk material. With ternary quantum dots, the composition may be varied continuously so

A scalable solid-state quantum computer based on quantum dot pillar structures

open access: yes, 2000
We investigate an optically driven quantum computer based on electric dipole transitions within coupled single-electron quantum dots. Our quantum register consists of a freestanding n-type pillar containing a series of pair wise coupled asymmetric ...
