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