Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

Entanglement—linking distant particles or groups of particles so that one cannot be described without the other—is at the ...

Quantum dots are widely used for their ability to emit single photons at specific wavelengths. These photons are created by electronic transitions in quantum dots and are ideal for encoding and ...
