I will try to link the two concepts in the following way. It is rough, descriptive, but contains the essential idea. Here we are talking about the so-called orbital angular momentum (OAM) of an electron orbiting around the nuclei. In classical mechanics, OAM is defined as $ \vec{L} \equiv \vec{r}\times\vec{p} $ where $\vec{r}$ is the position of the ...

I particularly like this example of a single qubit quantum classifier. The idea is to use a variational approach to do ‘data reuploading’ and create a non-linear classifier, which has similarities to a single hidden layer neural network. There’s an example implementation from Xanadu in Python along with a basic overview.

Some select examples of single qubit technology that has been used for decades: Atomic clocks are single qubit quantum information processors. (In fact, the natural transition frequency between the states of a specific qubit defines what humans mean by time.) NMR Spectroscopy is typically applied to single qubits. (Well, ensembles of single qubits, but ...

The source of noise in your system, and how to reduce it, is really dependent on the quantum computing architecture you're pursuing. As stated above the most successful quantum computers at the moment are of the superconducting qubit flavor. And as the articles suggest, the way to reduce noise is low temperature and low vibrations, and perhaps chip design(...

I read the article and it seems too rudimentary to provide a manual how to build a quantum computer home. It also contain some "half-truth" about quantum computers, e.g.: Quantum computers take advantage of strange properties from quantum mechanics to filter through possible solutions much more quickly than conventional computers. When someone asks about ...
