Researchers Suggest Quantum Dots as Media for Teleportation.
According to recent research, tiny clusters of atoms known as quantum dots may be excellent media for quantum teleportation, a physics phenomenon in which information – in the form of a quantum state, a very specific mathematical “signature” of an atom – can be transmitted almost instantaneously to a distant location without having to physically travel through space. Teleportation is one facet of quantum information science, a developing field that could have a major impact on computing and communications.
Here, researchers focus on semiconductor quantum dots containing as few as a thousand atoms of a semiconducting element, such as silicon, and having diameters as small as one nanometer. They are often referred to as “artificial atoms” because their behavior can be quite similar to a single atom.
For example, a semiconductor quantum dot's electrons can be confined in a way similar to how a single atom's electrons are bound. Therefore, a quantum dot can be described by a single quantum state, despite consisting of hundreds or thousands of atoms.
