Researchers achieve quantum confinement without shrinking materials by engineering a COF with confined excitons, enabling strong photoluminescence and nerve agent detection. (Nanowerk News) Quantum ...

In quantum technologies, emitter coherence time is a critical bottleneck. Traditional subradiant states—long-lived entangled states in waveguide QED—suppress collective decay through interference but ...

Quantum dots (QDs) are semiconductor nanocrystals that exhibit unique optical characteristics due to quantum confinement effects, which result in discrete electronic states and size-tunable emission ...

Quantum confinement is a physical effect that occurs when the size of a material—usually a semiconductor or conductor—is reduced to the nanoscale thereby restricting the movement of electrons or holes ...
