From smartphones and data centers to electric vehicles and next-generation quantum systems, the technology that powers daily ...

If we can harness the potential of quantum physics, modern computers may come to seem like plodding calculators in comparison with the machines of the future, says Chris Carter ...

Quantum physics began in 1900 when the German physicist Max Planck determined the scale of quantum phenomena. In 1905, Albert ...

In quantum mechanics, there is a concept called superposition. This means that, at the smallest scales, things can exist in multiple states at once. For example, an electron can be spinning both ...

Superposition is a concept from quantum mechanics: for example, an electron can exist as a superposition, or probability, of multiple locations. You can also think of superposition like a coin ...

which posits that a cat in a box could exist as simultaneously dead and alive until an observation or measurement of the system is made. Similarly, an electron in a superposition exists in ...

This superposition indicates that the moment the electron leaves the atom depends on the energy state of the remaining electron. If the latter is in a higher energy state, it is more likely that the ...

When Alice opens her box and sees a left-hand glove ... talking about when they say that a vertical spin up electron is in a quantum superposition of horizontal spins left and right.

The study reveals that although these electron vortices can be quantified macroscopically by a single integer describing their global topological invariance, microscopically, they are actually a ...

We call this a superposition. Scientists have been able to show this in the famous double-slit experiment, where a single quantum particle, such as a photon or electron, can go through two ...
