What is quantum size effect? What is a quantum leap in physics? Does quantum tunneling disobey special relativity? What modern-day discoveries are from quantum physics? Where is a quantum tunneling composite? What is 'k' in quantum mechanics?
What is quantum computing? Quantum computing is an emergent field of cutting-edge computer science harnessing the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers. The field of quantum computing contains a range of disciplines, ...
What Are Challenges to Quantum Memory? What is the Quantum Critical Point? What Are the Quantum Mechanics of Photosynthesis? What Are Some Tests for Quantum Gravity and the Theory of Everything?
This narrower definition is often simply called quantum yield; with the emission of light being implicit given the context. However, the terms fluorescence, luminescence and photoluminescence quantum yield are also commonly used. The quantum yield is reported as either a decimal fraction between 0 and...

Quantum computers The main goal of a quantum computer is to perform computations by using subatomic principles - namely, superposition and entanglement. While a standard computer uses bits, a quantum computer uses qubits (pronounced “Q-bits”). A qubit is not binary. A qubit can be a 1, or...
So, what is a Quantum dot? Quantum dots are ultra-fine semiconductor materials of nanoscale size. These dots produce different colors of light depending on the particle size—the larger the size the more red the color, and the smaller the size the more blue the color. They are able to em...
Alleviating the almost century old confusion, the correct laws of statistics and logic pinpoint the true oddity of quantum objects: duality. As it is shown in the first part of this short essay, duality plus conservation laws allow the violation of Bell’s inequalities for any spatio-temporal ...

However, the cumulative effect of Earth's gravity is what keeps everything anchored to the ground. Fundamental Forces Gravity is one of the four fundamental forces of nature, along with electromagnetic forces, the strong nuclear forces, and the weak nuclear forces. It is the weakest of the ...
