Atomic Quantum Dot Based Quantum Cellular Automata

Source: RedOrbit

It has been discovered that single silicon atoms on an ordinary silicon crystal serve as "quantum dots", enabling control over single electrons and thereby enabling revolutionary computation schemes that consume miniscule power. This new control over electrons may be put to use in a number of ways. For example, the "QCA" (quantum cellular automata) mechanism proposed by Craig Lent and co-workers at Notre Dame provides an architecture for an extrem ...

Chairman of Taiwan Semiconductor Manufac
The similarities between gated quantum dots and the transistors in modern microelectronics—in fabrication methods, physical structure and voltage scales for manipulation—have led to great interest in the development of quantum bits (qubits) in semiconductor quantum dots. Although quantum dot spin qubits have demonstrated long coherence times, their manipulation is often slower than desired for important future applications, such as factoring. Furthermore, scalability and ...

Physicists have used a scanning tunneling microscope to create quantum dots with identical, deterministic sizes. The perfect reproducibility of these dots opens the door to quantum dot architectures completely free of uncontrolled variations, an important goal for technologies from nanophotonics to quantum information processing as well as for ...

(Phys.org) —Los Alamos researchers have demonstrated an almost four-fold boost of the carrier multiplication yield with nanoengineered quantum dots. Carrier multiplication is when a single photon can excite multiple electrons. Quantum dots are novel nanostructures that can become the basis of the next generation of solar cells, capable of squeezing additional electricity out ...

"Quantum Heroes" New York Premiere
One of the most remarkable consequences of the rules in quantum mechanics is the capability of a quantum particle to penetrate through a potential barrier even though its energy would not allow for the corresponding classical trajectory. This is known as the quantum tunnel effect and manifests itself in a multitude of well-known phenomena. For example, it explains nuclear radioactive decay, fusion reactions in the interior of stars, and electron transport through ...
