Answer:
Properties. Geometrically, a quantum point contact is a constriction in the transverse direction which presents a resistance to the motion of electrons. Applying a voltage across the point contact induces a current to flow, the magnitude of this current is given by , where. is the conductance of the contact.

here is your answer
Explanation:
What are quantum properties?
The main properties of quantum mechanics are the quantification of energy (quanta), the wave particle duality, the uncertainty principle and the correspondence principle. Connection to Big Idea about energy: Electronic transition in atoms corresponds to a quantized energy.
What is a quantum give two examples?
A quantum is an indivisible unit of something - the smallest "package that it comes in." There are many examples: a photon of light, a molecule of water (in the sense that if you divide it, you don't have water anymore). Cash is quantized - the penny is the smallest unit of U.S. currency.May 18, 2009

What are the applications of quantum dots?
Potential applications of quantum dots include single-electron transistors, solar cells, LEDs, lasers, single-photon sources, second-harmonic generation, quantum computing, and medical imaging. Their small size allows for some QDs to be suspended in solution, which may lead to use in inkjet printing and spin-coating.
