*Electrons* are an [[Elementary Particles|elementary particle]] and they are the most ubiquitous carrier of negative electric charge. They are useful for [[quantum information]] since they carry [[Spin|spin]] which can be used to store [[Quantum Information|quantum information]]. In atoms, they populate the outer shell and counter the protons' positive electric charge in the core. An atom appears uncharged to the outside. ![[atom.excalidraw.light.svg]] While we usually imagine *electrons* as small point-like particles, they can also exhibit [[Wave|wave]] characteristics, i.e. they can [[Interference|interfere]] and diffract. The associated wave-characteristics are summarized in the [[De Broglie Wavelength|De Broglie wavelength]]. After all, electrons are quantum mechanical objects: just as [[Photon|photons]] show [[Wave-Particle Duality|particle and wave behavior]], so do electrons. In [[Quantum Simulation|quantum simulation]] and [[Quantum Computer|quantum computing]], electrons stored in [[Platform - Quantum Dots|quantum dots]] can be used to store and manipulate [[Quantum Information|quantum information]]. >[!read]- Further Reading > - [[Atom]] > - [[De Broglie Wavelength]] > - [[Platform - Quantum Dots]] > - [[Wave-Particle Duality]] >[!ref]- References
