A proton is just an ionized hydrogen atom, so it seems somewhat arbitrary to believe that a single hydrogen atom is a material, but a proton is not. Bound neutrons are stable, but free neutrons decay into a proton, an electron, and an electron anti-neutrino. Quantum field theory ascribes...
What is a quantum? A quantum (plural:quanta) is the smallest discrete unit of aphenomenon. For example, a quantum of light is a photon, and a quantum of electricity is anelectron.Quantumcomes from Latin, meaning "an amount" or "how much?" If something is quantifiable, then it can be ...

A semiconductor is a basic element or compound substance that conducts electricity in certain situations.
A QLED TV is a Quantum dot-based TV, and that Quantum dot material is what makes QLED TVs different from conventional ones. 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...
What is a qubit? A qubit is the basic unit of information in quantum computing. Qubits play a similar role in quantum computing as bits play in classical computing, but they behave very differently. Classical bits are binary and can hold only a position of 0 or 1, but qubits can hold...

Quantum algorithms work by storing and manipulating information in a way inaccessible to classical computers, which can provide speedups for certain problems. As silicon chip and superconductor development has scaled over the years, it is distinctly possible that we might soon reach a material limit ...
