Quantum dot cellular automata (QDCA, sometimes referred to simply as quantum cellular automata, or QCA) are a proposed improvement on conventional computer design , which have been devised in analogy to conventional models of cellular automata introduced by John von Neumann.
Individual quantum dots can be created from two-dimensional electron or hole gases present in remotely doped quantum wells or semiconductor heterostructures called lateral quantum dots. The sample surface is coated with a thin layer of resist and a lateral pattern is then defined in the resist by electron beam lithography .
Quantum dot computer, spatial-based (qubit given by electron position in double quantum dot) [9] Quantum computing using engineered quantum wells, which could in principle enable the construction of a quantum computer that operates at room temperature [10] [11] Coupled quantum wire (qubit implemented by a pair of quantum wires coupled by a ...
The quantum dot technology, which enabled high-definition QLED TVs sold by Samsung, Sony or TCL, traces its roots to early 1980s work by Ekimov.
Gates recently revealed in a Reddit AMA the one thing he'd like to see in his lifetime -- and his answer won't disappoint you.
Various models of quantum computation exist, but the most popular models incorporate concepts of qubits and quantum gates (or gate-based superconducting quantum computing). Superconductors are implemented due to the fact that at low temperatures they have infinite conductivity and zero resistance.
A double quantum dot. Each electron spin S L or S R define one quantum two-level system, or a spin qubit in the Loss-DiVincenzo proposal. A narrow gate between the two dots can modulate the coupling, allowing swap operations. The Loss–DiVicenzo quantum computer proposal tried to fulfill DiVincenzo's criteria for a scalable quantum computer ...
Different sized quantum dots emit different colour light due to quantum confinement. Quantum engineering is the development of technology that capitalizes on the laws of quantum mechanics. Quantum engineering uses quantum mechanics as a toolbox for the development of quantum technologies, such as quantum sensors or quantum computers.
