The IUPAC definition of quantum yield (Φ) is the number of a certain event occurring per photon absorbed by the system,1 However, it is most commonly written specifically for the emission of light (photoluminescence) by a system,2-5 This narrower definition is often simply called quantum ...
Learn how the fragility of quantum hardware lets us detect the undetectable and discover the principles and potential applications for quantum sensing.
solved the photoelectric effect problem with 'quantum' He proposed the hypothesis of 'light quanta' believing that the energy of light radiation itself is 'quantized' In other words light is made up of discrete 'energy packets' 'Energy packet' size is related to intensity which means continuity ...
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, ...
Together, quantum superposition, entanglement and interference enable enhanced computing power because when more qubits are added, capacity increases exponentially. However, today's quantum computers operate at a much smaller scale than is theoretically possible, largely because their quantum properties are ...
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...
Getting something from nothing is the dream of perpetual machine enthusiasts. Have we finally cracked the code? Read on to learn about quantum vacuum physics.

What is the quantum level?Quantum Mechanics:Quantum mechanics is the branch of physics which is concerned with studying how quantum effects manifest in the real world. These effects are often thought of as being weird and counter intuitive.
The first is the ability to capture the photon. This property is called quantum efficiency. If 100 photons hit the bucket and 40 of them are collected, the array has a quantum efficiency of 40 percent. The other important property is that of well depth or the capacity of the bucket. A ...
